Electrochemical investigation of chloramine T

Abstract Electrochemical measurement methods are suitable for examining the hydrolysis and reactivity of chloramine T. The individual species can be separated by means of capillary electrophoresis. Voltammetrical methods make it possible to judge selectively on the oxidation efficiency of individual substances. By coupling the coulometric determination with sample preparation techniques, e.g., stripping out, volatile chlorine can also be determined. The stability of chloramine T solutions was tested at various pH values and hydrolysis reactions are described. It is shown that chloramine T differs from other active chlorine donors and hypochlorite/chlorine with regard to its reactivity.
