Chlorine dioxide disinfectant has the characteristics of strong sterilization ability, no harm to humans and animals, and no secondary pollution to the environment. Chlorine dioxide is not only a broad-spectrum environmentally friendly sterilization disinfectant that does not produce carcinogens, but also shows significant effects in sterilization, food preservation, deodorization and so on.
First, the advantages of chlorine dioxide disinfectant analysis
1. Strong sterilization ability The oxidation capacity is 2.6 times that of chlorine, and the sterilization effect is about 5 times that of hypochlorous acid.
2. Low cost of use, small odor, activation rate up to =95%, fast activation speed.
3. Broad-spectrum sterilization Quickly kill all kinds of bacteria, fungi, viruses, protists, algae and giardia spores, cryptospores and spores-formed bacteria Quickly remove and degrade iron and manganese, phenols, sulfides, cyanides and other harmful substances.
4. No "three-factor" effect Non-toxic, harmless, no residue No irritation to the skin.
5. The PH value is widely adapted to not produce organic chlorides do not form trihalomethane and other substances.
6. Safe, efficient, stable, easy to transport.
Second, chlorine dioxide disinfectant testing items
1. Physical and chemical indicators: active ingredient chlorine dioxide content, arsenic content, heavy metal content (in terms of lead)
2, for drinking water disinfection, who is on duty after disinfection needs to meet the drinking water standard GB 5749
3. Stability
4. Microbial killing indicators: Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, Mycobacterium tortoise abscess subspecies, poliovirus, Bacillus subtilis black variant spores
Third, chlorine dioxide disinfectant testing standards
GB 26366-2010 Chlorine dioxide disinfectant hygiene standard
GB/T 20783-2006 Stable chlorine dioxide solution
Chlorine dioxide disinfectants are often used for disinfection of food processing utensils, disinfection of catering utensils, disinfection of vegetables and fruits, disinfection of drinking water, disinfection of swimming pool water, disinfection of hospital sewage, disinfection of urban water, and environmental or surface disinfection of other non-metallic medical devices. Therefore, in different application scenarios, the detection indicators that focus on it will also be different. These are all issues that we need to pay attention to in actual inspection.
