What is Chlorine Dioxide
Chlorine dioxide (ClO2) is used as an oxidizing microbiocide in industrial cooling water treatment, the meat, livestock and dairy industries, and many other food and beverage industry applications. It is also used as a bleaching agent in the pulp and paper industry, and as a disinfectant in municipal water treatment. Industrial waste treatment facilities use chlorine dioxide because of its selectivity for certain compounds, including phenols, sulfides, cyanides, and mercaptans. It is also often favored over chlorine as a disinfectant because it does not create as many toxic disinfection by-products (DBPs). The oil and gas industry uses chlorine dioxide for downhole applications and as a stimulation enhancement additive.
Why Test for Chlorine Dioxide?
Since chlorine dioxide is used as a disinfectant, it is typically measured to determine whether water disinfection programs are performing efficiently. Having high levels of chlorine dioxide indicates an overuse of chemical leading to lost profit while low levels represent inadequate disinfection.
The Maximum Residual Disinfectant Level for chlorine dioxide is 0.8 mg/L in drinking water.
About Our Test Kits
CHEMetrics offers a visual test kit that spans low and high measurement ranges. The test uses the standard DPD methodology for analysis of chlorine dioxide. The test ampoule turns pink and is compared against a color comparator to provide results in ppm.
