ABSTRACT

 

Chlorine dioxide exists as a free-radical monomer and typically reacts with organics as an oxidant with little or no chlorination. Chlorine dioxide highly effective at alkaline pH as an oxidant and is selective due to its unique ability to extract one-electron during oxidations to get reduced to chlorite. Chlorine dioxide is efficient and effective at low concentrations and less chlorine dioxide is required to obtain an active residual disinfectant. Based on experiences of our research group in various water treatment projects, particularly the oxidative degradation of textile dyes, the detailed chemistry and scope of chlorine dioxide as an oxidant in water treatment and its wide range of industrial applications will be described.
