Description

Bactericidal and antifungal agents prepared by combining precious metal elements with group 7B elements

The present invention relates to precious metals such as platinum (Pt), gold (Au), silver (Ag), palladium (Pd), copper (Cu) and nickel (Ni) and group 7B elements on the chemical periodic table, for example pullulor (F), The present invention relates to a bactericidal and antifungal agent for use as a pollution-free bactericide by combining elements such as chlorine (Cl), bromine (Br) and iodine (I) by chemical methods.

Conventional fungicides are mainly composed of chlorine compounds, and these chlorine fungicides not only cause disgusting odors, but also combine with other organic substances in the treatment of water, resulting in the formation of THM (trihalomethane), known as a carcinogenic substance. .

In addition, chlorine disinfectants can be used only in a limited environment in direct contact with the human body (eg swimming pools, baths, etc.) because of the severe irritation to the skin and eyes. Another disadvantage of chlorine disinfectants is the problem of severe corrosion of water pipes.

The present invention is described in detail below.

In general, bacteria causing diseases in plants and animals are various and various methods of breeding are complicated, so there are various ways of killing bacteria. Until now, sterilization and disinfection methods have been adopted: a) ozone sterilization method using oxidizing power of ozone, ultraviolet ray sterilization method using ultraviolet ray, c) low temperature and high temperature sterilization method using temperature difference, and d) chemical sterilization using chemicals. Method, e) radioactive sterilization method using radioactivity, and the present invention belongs to d). In other words, the sterilization of bacteria causing diseases in animals and plants is very important for the preparation of food additives, food preservatives, preservatives, agricultural and aquatic product treatment, and effective sterilizing agents for these sterilizations must be accompanied by antibacterial, deodorant, deodorant, and antifungal for various foods, It can be used for food additives, beverage preparation, kitchen utensils manufacturing, even packaging, plating surfactants, dyeing agents and the like.

Accordingly, the present invention is directed to the use of Group 7B elements of the Periodic Table and precious metals that do not cause oxidation and side effects that are capable of achieving the above-mentioned objectives chemically and physically.

Figure 1 shows the degree of corrosion that proceeds over time and different concentrations of fungicides in order to prepare for the sterilization effect of the conventional fungicides and fungicides of the present invention.

In the present invention, when the compound represented by the bactericidal mechanism AB is separated into A ⁺ ions and B ^- ions in an environment in which bacteria are propagated, the compound binds to an enzyme possessed by the bacteria and inhibits the growth of the bacteria. More specifically, when a noble metal (Pt, Au, Ag, Pd, Cu, Ni, etc.) and a group 7B element (F, Cl, Br, I) on the periodic table are chemically combined, an AmBn (m, n: real) type Compound is produced. The AmBn-type compound causes an ionization reaction of AmBn → mA ⁺ + nB ^- in the presence of water, and the metal ions and non-metal ions produced at this time bind to enzymes of bacteria and inhibit the growth of bacteria.

That is, the metal component A and the group 7 element component B are formed as an AmBn type compound by a chemical reaction, and the compound AmBn reacts in the presence of moisture in water or in an environment where bacteria are grown, as shown in Equation (1).

^{AmBn → mA + + nB - ......} (1)

The metal ions produced in this equation (1) are in perfect equilibrium with the ions in systems without external influences. However, assuming that bacteria exist in this system, the metal ions in equilibrium in equation (1) bind to the bacteria and at the same time non-metal ions are activated. These activated B ions have the ability to attack the bacteria again. Bacteria-attached metal ions react with -SH groups in enzymes necessary for growth and proliferation of myocytes, thereby paralyzing the function of enzymes. On the other hand, B ions are attached to the cell membrane of the bacteria to prevent the nutrients required by the bacteria to move into the bacteria.

In the present invention, the bactericidal bacterium generally has a positive or negative charge depending on the hydrogen ion concentration. In the case of the present invention, since A ⁺ and B ^-have both polarities at the same time, the bacterium may attack the bacteria regardless of the hydrogen ion concentration as described above. Can be. That is, the first feature of the present invention is that the sterilizing power is stronger than the conventional sterilizing agent and wider the sterilizing range since it is involved in A ⁺ and B ^- cations before sterilizing.

Conventional fungicides have a bactericidal effect only when the concentration of elements involved in the sterilization mechanism is 10PPM or more, but the present invention exhibits excellent bactericidal properties even when the concentration of the fungicide is 2PPM or less. That is, the conventional fungicide does not have a bactericidal action against Legionella and Vibrio bacteria below 10PPM. In particular, Legionella bacteria in the cooling tower and Vibrio bacteria present in seafood are inherently resistant to chlorine, so existing chlorine fungicides do not function, whereas the present invention is concerned with metal ions before sterilization. It can exhibit sufficient bactericidal power.

A second feature of the present invention is that the metal ions represented by A ⁺ remain effective even when combined with other materials that can be oxidized or ionized after use.

The third characteristic of the present invention is that it is harmless to human body because it has no smell and skin irritation.

A fourth feature of the invention is that it is not corrosive to metals. In addition, the most important feature of the present invention is that there is no generation of trihalomethane (THM) that is a carcinogen during constant sterilization.

THM is generally produced by combining organic acids present in the water source with chlorine and Br. Since the present invention is configured such that the organic acid, chlorine, Br and the like cannot be fundamentally combined, the production of THM can be excluded from the beginning. Chlorine in existing disinfectants combines with Cu and Fe to form compounds such as CuCl ₂ and FeCl ₃ to slowly corrode iron and non-ferrous metals, but in the present invention, the main element involved in sterilization is + state ion Since the ion concentration of is extremely low, the corrosiveness is hardly observed for the iron and nonferrous metals.

Figure 1 shows the results of the self-test shows the superiority of the product of the present invention. In this FIG. 1, the material used for corrosion used the weight of 50g as a copper plate of 99.9% purity. As can be seen here, the conventional products (10 ppm concentration of disinfectant) have a higher corrosion rate as time passes, but the products according to the present invention do not increase much due to the significant sterilization effect even if time passes even at a concentration of 2 ppm of disinfectant. It can be seen.

In order to describe the present invention in more detail below, an embodiment will be described in detail.

For the addition of the Group 7B element, an organic material containing the Group 7B was used, and only the organic material used was selected to be 99.999% or more. Two kinds of organic materials were added to distilled water, sufficiently stirred, and a chemical reaction was performed at 95 ° C. or higher. After the reaction, the produced material was stored in a refrigerator for 72 hours and filtered to separate only materials of 5 μm or less. The separated material was put into a vacuum evaporator and dried for 100 hours.

The finished sample was mixed with distilled water to adjust the concentration of the metal element to 0.1 ppm, 0.2 ppm and 0.5 ppm.
