Description
Chlorine dioxide is often used as an alternative disinfectant to chlorine in order to limit the formation of chlorination byproducts. However, the use of chlorine dioxide leads to the formation of chlorides and oxichlorine groups, such as chlorites and chlorates. It is therefore important to have a reliable analytical method to monitor the formation and presence of chlorine dioxide byproducts. Ion chromatography can be used for this purpose but it is expensive and complex and must be complimented by field methods to allow operators to carry out regular on-site analyses. This paper describes a method which is based on the oxidation of orthotolidine by chlorine dioxide (formed by chlorite under acidic conditions) or by chlorine (formed by chlorate under other acidic conditions). The paper also presents the results of a study undertaken to compare the results of the described method with those obtained using ion chromatography.
