【Chemical Name】
Chlorine Dioxide
Molecular formula: CIO2
Molecular weight: 67.46
Appearance: white tablet, powder, yellow-green solution
【Uses】
Chlorine dioxide acts as an oxidant, deodorant, biocide, preservative, bleach and so on.
Because of its strong sterilization ability, no harm to humans and animals, and no secondary pollution to the environment, it is very popular. Chlorine dioxide is not only a broad-spectrum environmentally friendly germicidal disinfectant that does not produce carcinogens, but also shows significant effects in sterilization, food preservation, and deodorization. Chlorine dioxide can also be used for bleaching, such as textile The chlorine dioxide bleached by paper mills can be replaced by chlorine dioxide.
