检测水样或废水中的游离氯或总氯含量

This method is used for the quantitative determination of Chlorine, Hypochlorite and Chloramine in water and wastewater using the potentiometric or Dead Stop titration method with phenylarisine oxide as titrant. The method is used for chlorine concentrations < 5 mg/L. The endpoint can be detected potentiometric using a combined platinum electrode (recommended) or amperometric using a double platinum electrode.
