Chlorite

Drinking water treated with chlorine or chlorine dioxide contains a mixture of different chlorine species. Their identification, especially at low concentrations, is still problematic because of the number of compounds produced, especially when mixtures of chlorine and chlorine dioxide are used. Thi

Effective use of chlorine dioxide as an alternative disinfectant in water treatment may require removal of the by! product chlorite ion (ClO2 ). The goal of this research was to investigate the use of ferrous iron (Fe2+) for the chemical ! reduction of ClO2 from drinking water in order to define the
