Abstract

A new method is developed for the calorimetric determination in water of chlorine (free and combined) with 3,3',5,5'-tetramethylbenzidine. The procedure proposed achieves a detection limit of 2 ng/ml and its sensitivity is greater than that of the methods used at present.

摘要

开发了一种新方法，用于通过3,3',5,5'-四甲基联苯胺以量热法测定水中的氯（游离氯和结合氯）。所提出的程序实现了2 ng/ml的检测限，其灵敏度高于目前使用的方法。
