Description

System of artificial eco-friendly tree improving air condition with reducing air pollution

The present invention relates to an eco-friendly artificial tree system for improving air pollution reduction, and more particularly, using a boron-doped diamond (BDD) electrode, a filter ball coated with titanium dioxide, and an advanced oxidation process (AOP) And using readily available water (drinking water, drinking water), it electrochemically oxidizes and decomposes high-molecular organic materials containing toxic harmful substances such as NOX and SOX, and converts them into eco-friendly materials and exists in the surrounding air. It sterilizes viruses, removes fine dust very effectively, suppresses the surrounding heat island phenomenon, acts like a tree, and at night, indirectly illuminates a certain area around it and improves air pollution reduction by detecting human approach and illuminating it brightly Eco-friendly artificial tree It's about the system.

Due to the recent rapid industrialization and acceleration of desertification in some areas, the atmosphere contains a large amount of dust, fine dust, and harmful harmful substances including NOX and SOX. There have been many reports of research cases that cause respiratory diseases, etc.

According to the research results of the National Institute of Forestry and Science of the Korea Forest Service as of November 18, 2016, trees absorb fine dust in the air (atmosphere) for volume growth and use them. It is known that the average amount of fine dust absorbed by one year-old tree is 35.7 g per year, 97.8 mg per day for 365 days, and 4075.3 ug per hour. However, many trees or forests have an environmental problem in that they do not sufficiently purify the air because the number of remaining trees is limited because large-scale logging and destruction are carried out by humans.

In these days, when problems of maintaining human health and creating a safe surrounding environment are emerging as serious social problems, various infectious diseases that had been relatively hidden in the past recur or new diseases that are difficult to predict occur, so disinfection for prevention and control is presented as an important problem. The necessity of quarantine and prevention for disinfection, sterilization, and sterilization of viruses and bacteria that cause these diseases is being discussed.

Viruses range in size from 20 to 250 nanometers (nm, billionths of a meter (m)), while bacteria are known to range in size from about 1 to 5 micrometers (um, millionths of a meter). .

Toxic compounds of ionic components such as lead, cadmium, sulfur oxide (Sox), nitrogen oxide (NOx), sulfur dioxide, ammonia, carbon compounds, etc., which are various pollutants due to industrialization or industrialization, heavy metals , metal compounds, etc. are being discharged in large quantities into the atmosphere.

On the other hand, in the process of burning fossil fuels used as fuels in the process of industrialization and industrialization, fine dust having a structure in which carbon components are surrounded by organic hydrocarbons, nitrates, metals, sulfates, etc. Fine dust easily penetrates into the body, and once infiltrated, it is not easily discharged from the body and accumulates, causing various fatal diseases and diseases. well known to appear.

Such fine dust (fine dust, particle dust matter) is generally a particulate matter having a particle size of 0.1 to 10 μm, and particulate matter of 2.5 to 0.1 micrometer (㎛) or less is classified as ultra-fine dust and suspended in the air. As it penetrates into the human body in the process of breathing while breathing, interest in health risks is increasing to the extent that it is managed separately at the government level.

Fine dust is 50 - 70 micrometers (um) in diameter and less than 10 micrometers (um), which is about 1/10 the size of a hair. Falling down, you face serious illness.

Fine dust containing nox and sox causes an inflammatory reaction in the bronchi, which causes or worsens asthma, chronic bronchitis, airway obstruction, etc. It can also cause infection. In addition, fine dust is recognized as an important risk factor for cardiovascular diseases such as myocardial infarction, stroke, heart rate abnormality, and sudden death.

Particles of fine dust can be composed of various types of contaminants agglomerated and attached to the nucleus of fine dust. When such fine dust is inhaled for a long time through breathing, etc., it is not filtered through the nasal mucosa and directly penetrates into the cells of the alveoli, and it affects the occurrence of asthma, lung disease, and even an increase in the premature death rate.

According to the results of many studies, long-term and continuous exposure to fine dust has adverse effects on health, and in the case of healthy adults, it is known that short-term inhalation does not suddenly cause bad body changes. However, it is very natural that the elderly, including general children, the elderly, and people with respiratory diseases, need special attention because they can have a direct effect on their health even if they are exposed for a short period of time, and it is very natural that even healthy people need attention.

In general, when fine dust penetrates the eyes, it affects allergic conjunctivitis, keratitis, etc., affects allergic rhinitis in the nose, bronchitis, emphysema, asthma, etc. It is known to cause cardiovascular diseases, including vascular damage, angina pectoris, and stroke, by infiltrating cells and circulating through blood vessels, further exacerbating various diseases as it makes it difficult to exchange oxygen and lowers the immune function of the human body.

Therefore, viruses with a size of 20 to 250 nanometers and bacteria with a size of 1,000 to 5,000 nanometers are mixed with fine dust with a size of 100 to 10,000 nanometers and ultrafine dust with a size of 100 nanometers or less and float in the atmosphere and enter the human body through respiration. It penetrates easily and causes various diseases.

In the following description, fine dust includes toxic compounds (chemicals) such as Knox, Sachs, lead, cadmium, sulfur dioxide, and heavy metals, which are various harmful bacteria, germs, mold, and pollutants in the core of fine dust. do.

As a prior art to solve some of these problems, the Korea Institute of Machinery and Technology and Ulsan Institute of Science and Technology applied for a patent. ' is there.

Advanced oxidation process (AOP) is a chemical treatment method or technology that removes organic or inorganic solvents from water or wastewater through an oxidation reaction using OH radicals (hydroxyl radicals). In reality, chemical processes using ozone (O3) and hydrogen peroxide (H2O2) or ultraviolet (UV) light are used in wastewater treatment.

As interest in energy and environment-related technologies continues to increase, water treatment technology to secure safe water resources has also been developed, and the treatment of difficult-to-decompose pollutants and toxic organic pollutants including NOX and SOX is a new technological field. It is emerging, and a technology that partially solves these problems is an advanced oxidation technology or an advanced oxidation process (AOP).

In the following description, the advanced oxidation process and the advanced oxidation technology have the same meaning and are selectively used according to the context.

Advanced oxidation process (AOP) is a chemical water treatment technology that oxidizes and decomposes pollutants using oxidizing agents, hydroxyl radicals (OH-, hydroxyl radical). -) can change to an oxidized state, but oxidative decomposition is impossible.

Hydroxide radicals in the advanced oxidation process (AOP) can be generated by directly applying energy such as gamma rays, high voltage discharge, and ultrasonic waves to water molecules, and a technology for generating hydroxyl radicals by applying high voltage discharge to water molecules is registered as a Korean patent. No. 10-1061227 (2011. 08. 25.) It is described in 'The number of hydroxyl radicals and hydrogen-oxygen gas generator using underwater plasma discharge and a system using the same'.

Advanced oxidation process (AOP) uses highly reactive hydroxyl radicals (*OH), etc., and these chemical species are the most powerful oxidizing agents in existence and can oxidize any compound dissolved in water, and control diffusion and reaction. It works through speed.

Hydroxyl radicals (*OH) actively react with various pollutants from the moment they are created to oxidize and decompose pollutants very quickly and efficiently into small inorganic molecules. Ozone, hydrogen peroxide, oxygen ion, etc.), energy sources or catalysts (ultraviolet rays, titanium dioxide, etc.) have to react

The AOP process utilizes at least 5 ppb to several hundreds of ppm under well-controlled reaction conditions to reduce the initial concentration of contaminants and reduce total organic carbon and chemical oxygen demand. In particular, it is useful for substances that are biologically toxic or not easily decomposed, such as aromatic compounds, pesticides, petroleum-based components, volatile organic compounds, etc. dissolved in wastewater. On the other hand, when used in the tertiary treatment of sterilizing the wastewater after the secondary treatment again, a large amount of pollutants are converted (mineralized) into stable inorganic compounds such as water, carbon dioxide, and salt. And by reducing the toxicity and chemical pollutants of the cleanly treated wastewater, the wastewater can be sent back to streams or conventional sewage treatment plants. In addition, it is often used in the tertiary treatment process to remove organic and inorganic substances that are difficult to handle due to their high oxidizing power and efficiency.

There are three major chemical principles of the AOP process.

first ; Formation of hydroxyl radicals (*OH).

Second: the initial reaction of the hydroxyl radical (*OH) to the target molecule and destruction of by-products.

Third: Subsequent reaction by hydroxyl radicals (*OH) until proceeding to final mineralization.

The synthesis mechanism of hydroxyl radical (*OH) is highly dependent on the type of advanced oxidation process technology, for example, ozonation, UV/hydrogen peroxide, and photocatalytic oxidation constitute different hydroxyl radical (*OH) synthesis pathways. .

one ; AOP based on UV light and hydrogen peroxide

two ; Ozone-based AOP

(두번째 오존 분자가 HO2-와 반응하여 오존 라디칼 음이온(ozonide radical)을 생성한다.)

(The second ozone molecule reacts with HO2- to produce an ozone radical anion.)

three ; Photocatalytic oxidation using titanium dioxide

(광촉매의 표면에 빛을 조사시 생기는 들뜸전자(e-)와 궤도에서(h-)를 생성한다.)

(Excitation electrons (e-) and orbitals (h-) are generated when light is irradiated on the surface of the photocatalyst.)

The reaction steps presented here are only part of the reaction sequence.

Although there is no orthodoxy on the detailed mechanism of the ‘three’ part, it is known that a clue regarding the oxidation process of the target molecule by the hydroxyl radical (*OH) in the reaction of the ‘two’ part has been confirmed.

In essence, the hydroxyl radical (*OH) is a radical molecule and acts as a highly reactive electrophile, and a hydrogen removal reaction and an addition reaction are required during the initial oxidation reaction.

Below is the oxidation mechanism of benzene using the hydroxyl radical (*OH).

The initial reaction of ‘two’ is an electrophilic reaction that decomposes the aromatic ring of (A) to form two hydroxyl groups (-OH) in the intermediate (C). Later, a hydroxyl radical (*OH) molecule grabs a hydrogen atom on one of the hydroxyl groups (-OH) and forms a radical species (D). This compound readily rearranges to the more stable (E) and (E) favorably undergoes oxidation of the hydroxyl radical (*OH) to yield 2,4-hexadiene-1,6-dione (F).

As long as there are enough hydroxyl radicals (*OH), oxidation continues after (F) and eventually (F) decomposes into small stable molecules such as H2O or CO2.

Advanced oxidation process (AOP) or advanced oxidation reaction has many advantages in water treatment. One of them effectively removes organic matter in a water-soluble state, and is efficient in changing or adsorbing pollutants to another state.

Due to the high reactivity of the hydroxyl radical (*OH), it reacts indiscriminately with all water-soluble pollutants and is widely used in the field of removing various organic pollutants.

When some heavy metals are removed in the form of precipitated M(OH)x, disinfection is possible, so water quality problems are solved at once. In addition, after the generated hydroxyl radical (*OH) is reduced, the hydroxyl radical (*OH) is reduced to finally generate water (H2O), so that other harmful substances are not left behind.

In the advanced oxidation process (AOP), there are titanium oxide/ultraviolet system, hydrogen peroxide/ultraviolet system, fenton, photo-fenton and electro-fenton system, and other systems are continuously being developed and developed. there is a situation. For example, a technique for increasing photocatalysis by administering a non-metallic element to titanium oxide or applying ultrasonic treatment to increase the generation of hydroxyl radicals (*OH).

The hot-filament chemical vapor deposition (HFCVD) method is a coating technique commonly used to coat diamonds. Diamond film deposition (coating) using HFCVD technology is suitable for the manufacture of tools, machine components, electrodes, etc. It has a characteristic and is generally well known.

The sterilization or disinfection process completely kills or annihilates the surface of the object to be protected or the bacteria distributed therein. Or, it is the process of making it safe by killing the pathogens in it and removing the power of transmission or infection, and sterilization is the safest form of disinfection.

In other words, disinfection is a process that removes pathogenic microorganisms (hereinafter referred to as 'microorganisms') or prevents contamination by microorganisms by suppressing infectivity by preventing them from being active. It is a process, and general microorganisms can be removed more easily than non-pathogenic microorganisms because their resistance is weak when exposed to the outside world or the atmosphere.

Microorganisms have different resistance to sterilization depending on their type, and in particular, in the case of spore-forming bacteria, they remain dormant under normal sterilization conditions and reproduce again when conditions improve. When it coexists with proteins such as , feces, etc., the resistance becomes much stronger than when it is suspended in physiological saline.

When a pathogen is transmitted, it is common to coexist with proteins, so there are various sterilization or sterilization methods for sterilization conditions depending on the object and purpose.

Disinfection (消毒) removes pathogens in order to prevent infection or transmission of diseases, in particular, it does not remove microorganisms such as non-resistant bacterial spores, and sunlight has less effect than sterilization, which is an extreme physical and chemical process that removes all microorganisms. Disinfect with heat, chemicals, etc.

In general, the chemical disinfection method is a method of removing bacteria with a disinfectant, and there are cases where liquid or gas is used.

It is relatively preferable that the disinfectant has strong sterilization power, is harmless, has a simple handling method, does not damage the object to be disinfected, is easy to produce, is inexpensive, and has no odor.

As disinfectants, phenolic acid (C6H5OH), cresol soap solution (cresol, CH3C6H4OH), formaldehyde (HCHO), sulphur (mercuric chloride, HgCl2), alcohol agent, reverse soap solution, chlorine agent (chlorine, bleach powder, sodium chloride difference) , chlorine inorganic compound), iodine, quicklime, hydrogen peroxide, medicated soap, and Mercurochrome solution are selectively used according to the purpose, object and type of infectious disease.

Phenolic acid uses a 3% concentration aqueous solution and sterilizes according to bacterial protein coagulation, cell lysis, and enzymatic action. Silver is known to be safe in sterilization power, and does not undergo chemical change even when stored for a long time.

Cresol soap solution does not dissolve well in water, so it is diluted with cresol soap solution 3 to 97 water and used to make cresol soap. is known to be very effective.

Formaldehyde is a gas made by oxidizing methyl alcohol (methanol), has a strong irritating odor, is well soluble in water, has a strong reducing power, has a sterilization effect even at low concentrations, has a simple generator using methyl alcohol, and is It is generated in a box that is made to be used for sterilization of objects inside.

Formalin is an aqueous solution containing 37% or more of formaldehyde and has a strong sterilizing power that microorganisms cannot recover by acting on proteins at high dilution concentrations, and has a strong sterilizing effect on spores. 1.5% aqueous solution is used, and its use is known to be suitable for disinfection of clothes, ceramics, wood products, celluloids, rubber products, etc.

Sulfur is colorless and odorless, insoluble in water, highly toxic and corrosive to metal, so a plastic container is used and the chemical solution is dyed with fuchsin, etc. - 0.5% aqueous solution is used, and it kills E. coli and staphylococcus in 5 to 10 minutes and has strong irritation to the mucous membrane, but cannot be used for disinfection of rubber products, metal products, etc.

Methyl alcohol has strong sterilization power in 70 to 75% aqueous solution and is mainly used for disinfection of resins, skin, instruments, etc.

Inverse soap solution is a surfactant with strong penetrating and sterilizing power, and is used as an aqueous solution of 0.1 to 0.5%. It is colorless, odorless, non-irritating, suitable for sterilization of resins, instruments, and containers, and is widely used in beauty, has little detergency, and is known to be ineffective against Mycobacterium tuberculosis.

Halogen elements, which are chlorine disinfectants, include fluorine, chlorine, and oxo. Chlorine, which forms a protein and halogen complex in living cells, stops cellular metabolism and kills cells, is a gaseous state with great sterilizing power, but has a strong irritant effect. It is used for large-scale disinfection of tap water and sewage due to its over-corrosiveness. Bleach powder (chlor-lime CaOCl2) generates chlorine in water and sterilizes it. And sodium hypochlorite (NaOCl) sterilizes by element chlorine generated in solution.

Iodine has a strong sterilizing power like chlorine, but it has fewer side effects on the skin and mucous membranes in dense concentrations. It has the disadvantage of roughening the sensitive skin.

Used for disinfection of manure bins, trash bins, sewers, water tanks, etc. It has the drawback that it is ineffective against Mycobacterium tuberculosis and spores, and the advantage is that it is suitable for disinfection of a wide area because it is cheap.

Oxidizing agent disinfectants such as hydrogen peroxide (H2O2) are agents that stop cell metabolism by oxidizing sulfurhydryl (-SH) groups, and are used for disinfection with 2.5 to 3.5% aqueous solution (oxyfull). However, sometimes it sterilizes by oxidizing pathogens with a liquid that smells like ozone.

The disinfection targets for each type of infectious disease are as follows.

First: typhoid, paratyphoid, cholera. In the case of dysentery, it is an oral infection, which is an infectious disease of the digestive system, and the patient's excrement, vomit, leftover food, tableware, and toilet become a problem.

Second: In case of smallpox or scarlet fever, the patient's runny nose, sputum, mucus, contaminated equipment, clothing, bedding, transport equipment, food equipment for the patient, bedroom floor, caregiver. Disinfect the contact person's body and clothing.

Third: In the case of diphtheria, disinfect the runny nose, sputum, contaminated equipment, tableware, books, toys, bedding, other objects in the room, and the caregiver's clothing and body.

Fourth: In the case of polio, it is equivalent to the disinfection of dysentery, but it is equivalent to the disinfection of diphtheria at the beginning of the outbreak.

In order to reduce the damage caused by pathogens, continuous quarantine and disinfection using various methods is mobilized in vulnerable areas, and sanitary pests such as flies and mosquitoes are exterminated, thereby preventing infectious diseases that are prone to infectious diseases in advance.

Food-borne diseases include oral infectious diseases such as cholera, dysentery, and typhoid; common human diseases such as tuberculosis, anthrax, brucellosis (salmonellosis), and bird flu (AI); There is food poisoning (bacteriality, natural poison, chemical substances, other factors), and if classified according to the cause of production, the tolerance for diseases caused by harmful and toxic ingredients of the original ingredients of food raw materials and production, growth, manufacturing, processing, and storage of food In the process of distribution, consumption, etc., harmful or toxic substances are mixed or polluted from the outside, which causes exogenous diseases, and toxic substances are generated by physical, chemical, and biological factors during the manufacturing, processing, storage, and distribution of food. There is an attraction that causes

In addition, the outbreak of an infectious disease requires the source of infection, the route of infection, and the susceptibility of the host.

Most infectious diseases occur and spread when three conditions of infection source, infection route, and susceptibility are met. Habituation such as disinfection is important.

Meanwhile, chlorine dioxide (ClO2) was first discovered by Humphrey Davy in 1814, and since its use as a disinfectant for water treatment was proposed by Berge in 1900, it has been widely used for drinking water sterilization, odor removal, and bleaching in the United States and Europe. In particular, it has been found since 1972 that chlorine dioxide does not react with organic pollutants in water to produce trihalomethane, a carcinogen, unlike chlorine.

However, domestic law (in the case of aqueous solution) restricts its use to the removal of heavy metals such as iron (Fe) and manganese (Mn) by concurrent (post-treatment) treatment with chlorine. : H7 (E. coli O157: H7), Salmonella sp., the efficacy of reducing the level of at least 1 in 100,000 is presented as a disinfectant standard, and the efficacy of chlorine dioxide is It satisfies these regulatory standards of It is especially difficult to remove this bacteria, but Listeria has a strong enough vitality to survive in a refrigerator or freezer, and it is known that it is difficult to remove its activity.

One of the advantages of chlorine dioxide sterilization is that it is applied to the processing process before and after harvesting apples, and it is used in small units that do not have heat sterilization equipment to remove contaminants, and there is no problem in that the taste of the fruit changes according to heating.

Chlorine dioxide has low risk in most environmental fields and kills bacteria and viruses, and chlorine dioxide solution is effective in maintaining the freshness of foodstuffs and disinfecting, sanitizing, and purifying and sterilizing certain places. Therefore, liquid chlorine dioxide water that maintains the freshness of all foods for human and animal health and provides a living environment that minimizes viruses and bacteria can be used in any space, especially for maintaining the freshness of fruits and vegetables and extending their lifespan do.

Chlorine dioxide has strong oxidizing and sterilizing power, has a melting point of -59 ℃ and a boiling point of 11 ℃, is a gaseous substance at room temperature, has a solubility of about 3000 ppm (mg/l) in water at room temperature and normal pressure, and is explosive when the gas concentration in the air is 10% or more It is used for sterilization, disinfection, deodorization, bleaching, etc. A process of diluting a high concentration of chlorine dioxide is essential for the production of sterilizing water using chlorine dioxide.

Since transport and storage of such chlorine dioxide is relatively dangerous, transport and storage are prohibited, and it is very common to directly produce chlorine dioxide at the site where it is needed.

It is known that there is about 1.4 billion Km** of water on Earth, and it is known that the available fresh water is 0.01% of that. If the volume of Mt. Baekdu is converted to 1400 Km** in order to estimate the capacity of available fresh water and make comparative calculations easier, it is equivalent to 100 times the volume of Mt. Baekdu. On the other hand, as desertification is progressing in certain areas due to the shortage of water for living, agriculture, and industry due to the increase of the population and global warming, securing and protecting water resources can be an important practical problem.

In order to electrolyze water, the activation energy of the overvoltage required to generate the spark of the shock discharge is required.

Overvoltage is a phenomenon in which a voltage (generally +5% or more) higher than the maximum voltage value appearing between two-point lines during normal operation is supplied for a long time (generally 1 second or more). It is defined as an excess potential voltage exceeding the peak value of the voltage difference occurring while the same reaction as the voltage occurring is reversibly balanced at the same electrode.

In general, the overvoltage generated by a platinum (Pt) electrode or an insoluble metal-coated electrode (DSE: Dimensionally stable electrode) is several 100 millivolts (mV) or less, whereas the BDD (boron-doped diamond) electrode The overvoltage is very large, above 1 volt (V).

In the case of electrolysis of water, a noble potential is maintained at the anode to generate reactive oxygen species of OH groups (HO*), hydrogen peroxide (H2O2), and ozone (O3) in addition to O2 generation.

When ultrapure water is electrolyzed in a two-room electrolyzer using an ion exchange membrane, hydrogen peroxide (H2O2) and ozone (O3) are simultaneously synthesized in large quantities at the BDD electrode, and OH groups are (HO*) is detected.

In an electrolytic cell using a BDD electrode, ozone is generated by an advanced oxidation process (AOP) containing ozone (O3) as a main component, and is generated by the following chemical formula.

Formula 1 ---

An electrode made of lead dioxide (PbO2), platinum (Pt), titanium dioxide (TiO2), tin dioxide (SnO2), and registered trademark DSE has less oxidizing power, lacks stability, and can pass a large current density than a BDD electrode. There is no problem.

We will examine the characteristics of the BDD electrode to electrolyze inorganic substances.

When 0.5 mol (mol) dm**-3 of salt (sodium chloride, NaCl, sodium chloride) and 0.2 mol dm**-3 of sodium sulfate (Na2SO4) aqueous solution are used

At the anode of platinum (Pt), Cl2 is generated in an aqueous salt (NaCl) solution, and O2 is generated in an aqueous sodium sulfate (Na2SO4) solution.

The anode of BDD produces (generates) hypochlorous acid (HClO) more than twice as fast as the anode of platinum (Pt), and the raw material salt is oxidized to perchlorate ion (ClO4-).

The BDD electrode, which is oxidized with perchlorate ions (ClO4-), exhibits better performance than the platinum (Pt) electrode. In addition, the BDD electrode can obtain a current efficiency of 70% or more in a persulfate ion (S2O82-) aqueous solution.

In low-temperature electrolysis using a BDD electrode with carbonate and alkali of percarbonate ion (C2O62-) as raw materials, the efficiency is three times higher than that of a commercially available platinum (Pt) electrode.

Urea acid (IO3-) can synthesize perurea ions (IO4-) with high efficiency.

In addition, the BDD electrode attracts attention as an electrode replacing graphite and nickel (Ni) in gas synthesis of fluorine (F2) and fluorine nitride (NF3) in molten salt.

The characteristics of the BDD electrode to electrolyze organic matter will be examined.

The BDD electrode has excellent properties of decomposing carbon dioxide (CO2) in decomposition target substances such as formic acid and phenol compared to conventional electrodes, and is also suitable for organic wastewater treatment applications that decompose organic compounds into small molecules by redox. Many reports are known.

The decomposition methods of organic matter include ① direct electrolysis, ② indirect electrolysis by OH groups formed on the electrode surface, ③ indirect electrolysis by active species such as ozone, hydrogen peroxide, and peroxide intrinsic to the electrolyte, and ④ indirect electrolysis by OH groups generated from active species. .

Because BDD electrodes generate indirect reactions, they are useful for decomposing and sterilizing low-concentration target substances.

For example, the cyan complex can be decomposed with a PbO2 electrode, but the use of a BDD electrode enables decomposition with a smaller amount of electricity, and the size or scale of the device can be reduced.

Since the decomposition potential of formic acid is lower than the O2 generation potential, the oxidation reaction can proceed easily. The total organic carbon (TOC) attenuation ratio corresponding to the concentration of formic acid in aqueous solutions of Na2CO3 and NaHCO3 is remarkably superior to the BDD electrode.

On the other hand, since the decomposition potential of phenol (C6H5OH) is lower than the O2 generation potential, the oxidation reaction can proceed easily. If the BDD electrode is installed in the electrolytic cell on the pipe and chemical plating wastewater treatment is performed, the remaining hypophosphorous acid, phosphorous acid and organic compounds can be oxidized and decomposed at the same time as metal is recovered on the cathode surface of the BDD electrode. It has the advantage of being able to reduce

Tests of decomposing organic substances contained in industrial and industrial water using BDD electrodes have been reported a lot. It is noteworthy that TOD and Chemical Oxygen Demand (COD) can be reduced, decomposition of hard-to-decomposable chelating agents and fluorine-based surfactants are possible, and brightening agents can be decomposed and recovered and reused in plating wastewater.

By using the BDD electrode, it is possible to decompose the soil water in the agricultural and livestock industry by removing and decomposing the nitrogen component present in the fertilizer and livestock feed. It is known that it is possible to decompose pesticides and herbicides such as environmental hormones and organic phosphorus compounds (Methamidophos), which have a serious impact on the ecosystem.

The BDD electrode is also suitable for the generation of functional electrolytic water and ozone water. The BDD electrode is an on-site synthesis technology that replaces the existing cleaning and disinfecting chemicals, and the hassle of preservation and management of chemicals can be omitted and the amount of chemicals used can be reduced.

The BDD electrode has high durability and is also used for cleaning electronic parts. Compared to sodium hypochlorite (NaClO4), acidic electrolyzed water contains a lot of HClO that does not dissociate, so its sterilization power is several dozen times higher.

In the electrode-membrane assembly, in which the rod-shaped BDD anode was wound with a band-shaped fluorine resin-based ion exchange membrane and a cathode ray, the H2 generating electrode, the ozone water concentration increased as the current increased. At a Cl- concentration of 1 mol dm-3 or less, ozone water is generated, and at a Cl- concentration of 3 mol dm-3 or more, HClO is generated.

In the case of producing HClO using a BDD electrode, a Cl- concentration of 3 mol dm-3 or more is preferable.

H2 gas can be separated from the cathode by winding the membrane on the sheet of the diaphragm and the cathode ray on two rod-shaped BDD electrodes and making the gap between the anode and the membrane on the sheet a flow path. Since the separate electrode maintains a high partial pressure of ozone gas, it is possible to generate ozone water with a high concentration three times that of the mixed electrode.

BDD electrodes can be usefully applied to sensors for detecting contaminants, electrolytic synthesis of peroxides, sterilization wastewater treatment, valuable metal recovery, deodorization, plating, electrodialysis, and electrolytic processing, and simple direct and indirect electrolysis can be expected. It is confirmed that there is an advantage in constructing a reaction field and reaction system of a high active material including the negative electrode, the diaphragm, and the electrolyte.

Diamond is colorless, transparent and strong, so it is used for industrial or jewelry purposes, but it is being developed and used as an electrochemical electrode material to prevent pollution of the global environment and secure water resources. Since diamond has high activation energy, it has the advantage of strong durability even at high voltage.

Although diamond is a semiconductor with a large energy gap, it is durable and can reduce its electrochemical resistance by adding additives. Recently, Permelec Electrode developed a diamond-coated electrode with boric acid added to secure water resources by coating a diamond film. Diamond-coated electrode is an eco-friendly electrochemical technology that oxidizes and decomposes organic substances in polymers and converts them into substances. Electrochemical decomposition has the advantage of improving the environment and securing water resources to prevent global warming.

In addition, diamond-coated electrodes generate perchlorate ions, hypochlorous acid, persulfate ions, and percarbonate ions to decompose, sterilize, bleach, and decolorize organic substances. Ozone and hydrogen peroxide are generated 10 to 300 times at the anode than the platinum, iridium dioxide, and lead dioxide electrodes of The US Food and Drug Administration is developing food storage and sterilizing agents with boric acid-added diamond electrodes, and it is also used in the development of electrolytic hexagonal water for human organ function recovery.
