Chlorine Dioxide - Chemical Safety Facts
2022年10月14日 · According to EPA, chlorine dioxide is used “in public water-treatment facilities, to make water safe for drinking.” When chlorine dioxide is added to drinking water, it helps destroy bacteria, viruses and some types of parasites that can make people sick, such as Cryptosporidium parvum and Giardia lamblia .
Chlorite and chlorate are disinfection by-products resulting from the use of chlorine dioxide as a disinfectant and for odour and taste control in water. Chlorine dioxide is also used as a bleaching agent for cellulose, paper pulp, flour and oils.
Chlorine Dioxide & Chlorite | Public Health Statement | ATSDR
Chlorine dioxide is used as a bleach at pulp mills, which make paper and paper products, and in public water-treatment facilities, to make water safe for drinking. It has also been used to decontaminate public buildings. Chlorine dioxide is soluble in water and will react rapidly with other compounds.
Chlorite occurs in drinking-water when chlorine dioxide is used for purification purposes. The levels of chlorite in water reported in one study ranged from 3.2 to 7.0
