采用浸蜡碳电极，建立了一种快速、灵敏的水中游离氯的电分析方法。该方法可以区分游离氯和其他组合氯。二氯异氰尿酸钠是一种广泛用于游泳池消毒的活性氯化合物，被选为本研究的模型系统。讨论了试剂、计时电流法、碘量法、灵敏度和精密度、温度、反应速率、pH值和离解。包括17个参考文献、图表。

A rapid and sensitive electroanalytical method has been developed for measuring free chlorine in water by using a wax-impregnated carbon electrode. This method can differentiate free chlorine from other combined chlorine species. Sodium dichloroisocyanurate, an active chlorine compound widely used in swimming pool disinfection, was chosen as the model system for the study. Reagents, chronoamperometry, iodometry, sensitivity and precision, temperature, rate of reaction, pH, and dissociation are discussed. Includes 17 references, figures.
