The principle of sodium hypochlorite sterilization

The main action of sodium hypochlorite disinfection is to form hypochlorous acid through its hydrolysis, and hypochlorous acid is further decomposed to form new ecological oxygen [O]. The extremely strong oxidizing nature of the new ecological oxygen denatures the proteins and other substances on bacteria and viruses. , Thereby lethal pathogenic microorganisms. Secondly, in the process of sterilization and virus killing, hypochlorous acid can not only act on the cell wall and virus shell, but also because the hypochlorous acid molecule is small and has no charge, it can also penetrate into the bacteria (virus) body and interact with the bacteria (virus) body. Organic polymers such as proteins, nucleic acids and enzymes undergo oxidation reactions to kill pathogenic microorganisms. Third, the chloride ions produced by hypochlorous acid can also significantly change the osmotic pressure of bacteria and virions, causing cells to lose activity and die.

Summary of the principle of sodium hypochlorite generator

The main reaction process of sodium hypochlorite generator electrolysis can be expressed by the following equation:

NaCl+ H2O = NaClO + H2↑

Electrode reaction: anode: 2Cl--2e- → Cl2 cathode: 2H2O + 2e- → H2 + OH-

Solution reaction: 2NaOH + Cl2 → NaCl + NaClO + H2O

The electrolysis process of the electrolytic brine type sodium hypochlorite generator is an electrochemical reaction process. Its only raw materials are salt and water. The sodium hypochlorite solution is made of pure quality. Although the chemical principle is simple, there are many technical indicators that affect the economy. So sodium hypochlorite occurs The design of the electrolysis electrode of the electrolytic device should consider various factors, and design and manufacture according to the characteristics of compact and reasonable structure, energy-saving operation, convenient operation and maintenance, high reliability of operation, and long service life of the equipment. The sodium hypochlorite solution is accurately dosed, safe to operate, easy to use, easy to store, non-toxic to the environment, and there is no air leakage, and it can be dosed under any environmental working conditions.
