At present, with the outbreak of the epidemic, hypochlorite water in water treatment equipment is gradually recognized by many people. hypochlorite can decompose to form new ecological oxygen, and the strong oxidation of new ecological oxygen causes denaturation of substances such as proteins on bacteria and viruses, thereby killing pathogenic microorganisms.
In the process of sterilization and virus killing, hypochlorous acid can not only act on the cell wall and virus shell, but also penetrate into the body of bacteria (viruses) due to its small and uncharged molecules. It undergoes oxidation reactions with organic polymers such as bacterial (virus) proteins, nucleic acids, and enzymes, thereby killing pathogenic microorganisms. At the same time, chlorine ions produced by hypochlorite can significantly change the osmotic pressure of bacteria and viruses, making their cells lose activity and die.
Hypochloric acid has a pH value close to that of the human body, mild and non irritating, colorless and odorless, with high stability. It can directly come into contact with the skin, suitable for the elderly, young, pregnant women, and sensitive muscles. In the implementation of GB/T36758-2018 in April 2019, it was specified that hypochlorous acid can be used for air disinfection, directly in contact with human hands, skin, and mucous membranes.
In aqueous solution, hypochlorite is partially ionized into hypochlorite ions (also known as hypochlorite anions) and hydrogen ions. Salt containing hypochlorite is called hypochlorite. The main salt in hypochlorite is calcium salt, which is an effective component of bleaching powder (a mixture of calcium hypochlorite and basic calcium chloride).
