Chlorine dioxide sterilization

DAWT·2022-05-09

Introduction

Chlorine dioxide disinfectant is an internationally recognized high-efficiency disinfectant and sterilizer. It can kill all microorganisms, including bacterial propagules, bacterial spores, fungi, mycobacteria and viruses, and these bacteria will not develop drug resistance. Chlorine dioxide has a strong adsorption and penetration ability to the cell wall of microorganisms, can effectively oxidize enzymes containing sulfhydryl groups in cells, and can quickly inhibit the synthesis of microbial proteins to destroy microorganisms.

Sterilization principle

Chlorine dioxide has good adsorption and permeability to the cell wall, and ClO2 releases new ecological oxygen and hypochlorous acid molecules when it contacts with microorganisms to produce a strong sterilization and disinfection effect. Electron atoms or groups (such as enzymes containing sulfur groups in amino acids or sulfides, nitrides, etc.) attack, forcibly plunder electrons to oxidize and decompose amino acids in microorganisms, inhibit their growth and kill them, so as to achieve disinfection and sterilization. purpose of bacteria. During the sterilization process, protein denaturation has no effect on higher animal cells, and there is no irritating odor of chlorine. Under normal circumstances, chlorine dioxide does not form chlorinated alkanes with alkanes, and reacts with most aliphatic and aromatic hydrocarbons, and does not produce carcinogenic organic chloroform, and its residues are water, trace sodium chloride and carbon dioxide. and other non-toxic substances.
