Abstract: Chlorine and chloramines are the most commonly used disinfectants for tap water, which are strictly controlled in dialysis water, and the maximum allowable concentrations are specified in industry standards. However, the consideration of hemodialysis industry is mainly focused on the daily monitoring of the concentration. The source, composition, hazards, removal and detection methods of total chlorine in dialysis water are poorly understood, and are only partially involved in the literature. This paper comprehensively and systematically compiles and summarizes the knowledge of the sources, effects, detection and removal of total chlorine in dialysis water with reference to the domestic and international literature, so as to provide detailed references and guidelines for the study and work in the industry practitioners.

Key words: Dialysis water, Free chlorine, Total chlorine, Chloramine
