Description
Technical field
The present invention relates to a kind of method of utilizing the preparation of natural mineral pyroelectric function material tourmalinite to be rich in the alkalescent water of hydroxyl radical free radical, belong to functional crystal material pyroelectricity catalytic chemistry field.
Background technology
The World Health Organization (WHO) is according to the long-lived geographic a large amount of investigation results in the world are analyzed, the wherein standard that proposes drink water is: weakly alkaline water, the pH value is weakly alkaline, it can in and body inner acidic toxin, the acid-basicity of adjustment body fluid, can also active cells, improve self resistance against diseases of body.The secret of longevo's good health and a long life that Here it is.
Hydroxyl radical free radical (OH) is a kind of important active oxygen, is to lose an electronics by hydroxide radical (OH-) to form from molecular formula.Hydroxyl radical free radical has extremely strong electronic capability oxidation capacity just, oxidizing potential 2.8v.It is the oxygenant that occurring in nature is only second to fluorine.In recent years, concentration height and constitutionally stable organic waste water constantly occur, and organic waste water how to remove these difficult degradations has effectively become the hot issue of water treatment.Utilize electricity to give birth to the application of hydroxyl radical free radical in treatment of Organic Wastewater and caused that people pay close attention to greatly.Hydroxyl radical free radical (OH) has high oxidizing potential (2.8V) because of it, and its oxidation capacity is extremely strong, with most organic pollutants chain reaction fast can take place, and non-selectivity objectionable impurities is oxidized to CO2, H2O or mineral salt, non-secondary pollution.There are at present many investigators to utilize OH to handle the research of organic waste water both at home and abroad.The approach that produces OH is more, mainly contains Fenton method, oxidizing, flocculating method, ozone method, ultrasonic degradation method and photocatalytic method.Along with China's rapid economy development; environmental pollution particularly water pollution problems is serious further; environment protection and water treatment problems more and more cause people's attention, demand developing water technology simple, efficient, natural, green, that environmental protection is of value to people's life health urgently and obtain alkalescent water and produce hydroxyl radical free radical.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of method of utilizing the tourmalinite preparation to be rich in the alkalescent water of hydroxyl radical free radical is provided.
Summary of the invention
The present invention utilizes the pyroelectricity katalysis of natural mineral pyroelectric function material tourmalinite, by the effect acquisition alkalescent water of tourmalinite to water, and under the fluctuation effect of temperature, utilize tourmalinite that the pyroelectricity katalysis of water is produced hydroxyl radical free radical, finally obtain the pH value between 7.00～8.55 alkalescent water and be rich in hydroxyl radical free radical (active oxygen), that this method has is with low cost, easy and simple to handle, environmental protection, nontoxic, pollution-free and can long-term reusable advantage.
Detailed Description Of The Invention
Technical scheme of the present invention is as follows:
A kind of method of utilizing the tourmalinite preparation to be rich in the alkalescent water of hydroxyl radical free radical, step is as follows:
(1) addition by 1～100g/L adds tourmaline powder in water, stir and to make suspension, the pH value between 7.00～8.55,
(2) suspension that then step (1) is made is warming up to 78～82 ℃ of maintenances 8-10 minute, is cooled to room temperature, circulates so repeatedly 25-30 cycle.Can utilize tourmalinite that the pyroelectricity katalysis of the aqueous solution is produced hydroxyl radical free radical by heating up repeatedly, lowering the temperature, in the pyroelectricity catalytic reaction process, can make the aqueous solution keep suspended state by stirring.
Intensification in the above-mentioned steps (2) adopt electrically heated, steam heating or utilize solar light irradiation nature heating system all can,
Being cooled to room temperature and can cooling off by recirculated water in the above-mentioned steps (2) also can adopt other cheap cool-down methods to cool off.Wherein preferably cool off by recirculated water.
Because hydroxy radical qiao character is extremely active, the transformation period is extremely short, and directly the intravital OH of detection of biological is very difficult.Therefore, when needs detect hydroxy radical qiao be, can select with Whitfield's ointment as trapping agent, OH attacks Whitfield's ointment and generates 2,32 resorcylic acids (2,32DHBA) with 2,52 resorcylic acids (2,52DHBA), utilize high-efficient liquid phase chromatogram technology (HPLC) to detect 2,32DHBA and 2,52DHBA infer the content of OH indirectly.Specific practice is, in the suspension that above-mentioned preparation method's step (1) makes, adds Whitfield's ointment by the addition of every liter of suspension 3～6mg, is stirred to dissolving fully.To give more detailed explanation to this in an embodiment.
Natural mineral tourmaline (Tourmaline) is commonly called as and is " tourmaline ".Tourmalinite is rich in volatiles boron and water, and fecund also has output in metamorphosed rock and the metamorphic deposit in pegmatite and pneumatoilitc solution ore deposit.Tourmalinite is human piezoelectricity, the pyroelectricity material of finding the earliest.Its piezoelectricity can be used for radio industry; Its pyroelectricity can be used for infrared acquisition, refrigeration industry.Bright in colour, transparent person can make raw material for gem (being commonly called as tourmaline).
The present invention is applied to pyroelectricity catalytic chemistry field with natural mineral tourmaline, has utilized the crystalline structure of natural mineral tourmaline uniqueness and the characteristics of pyroelectricity.In the structure of tourmalinite, there is great amount of hydroxy group, the fracture of the valence link that causes in crushing process on the tourmalinite surface, tourmalinite reason such as surface metal positively charged ion disappearance in the aqueous solution forms great amount of hydroxy group again on the tourmaline particles surface, thereby causes the aqueous solution to be weakly alkaline.And because tourmalinite intrinsic structure has the characteristics of unidirectional pole axis structure, the individual particle of complete crystallization can be considered as the ferroelectrics of poling, under thermal equilibrium state, bound charge appears in the near surface near the polarization vector two ends, these bound charges are shielded by the free charge of equivalent opposite sign, under the condition of envrionment temperature fluctuation, polarizability changes along with variation of temperature, original free charge can not shield bound charge more fully, so free charge appears in the surface, make the end at the tourmaline particles positively charged have the stronger ability of obtaining electronics and have very strong oxidation capacity, can be with the OH of its surface adsorption
-And H
2O is oxidized to the OH hydroxyl radical free radical.The generation scope of hydroxyl radical free radical is between 1.2nmol/L～12.5umol/L in the alkalescent water that method of the present invention obtains.
The present invention utilizes tourmalinite that the effect of water is obtained alkalescent water, and under the fluctuation effect of temperature, utilize tourmalinite to the pyroelectricity katalysis of water produce that hydroxyl radical free radical carries out that the method for water treatment is with low cost, easy and simple to handle, environmental protection, nontoxic, pollution-free, the advantage that can reuse for a long time and be easy to promote.Can be widely used in curbing environmental pollution, water treatment, virus killing, antibiotic, soil modification, clothes, finishing material etc.
