Colorimetric determination of chlorine dioxide in drinking water, reservoirs and disinfectant solutions
At a pH value of 5-6 chlorine dioxide reacts with N,N-diethyl-1,4-phenylene diamine (DPD) to form a red-violet dye.
Chlorine dioxide and other oxidizing reagents (indicated as chlorine)
Chlorine dioxide has a significantly higher oxidizing power than chlorine. Thus, is can still attack such bacteria, spores and viruses that chlorine cannot affect anymore. Additionally, as the effect of chlorine dioxide is independent of water pH value, it leads to biofilm-free systems.
