摘要
本文总结了我国水中余氯检测标准现状,从检测方法、方法原理、余氯限值等方面对现行标准进行了对比分析.同时对利用3,3',5,5'-四甲基联苯胺比色法测量水中余氯,从测量时间、读数时间、水样温度、试剂量方面提出方法改进.并对我国在线实时监测水中余氯提出了建议.
Abstract
This article summarizes the current status of residual chlorine detection standards in water in China,and compares and analyzes the current standards from the aspects of detection methods,method principles,and residual chlorine limits.At the same time,method improvements were proposed for measuring residual chlorine in water using the 3,3',5,5'-tetramethylbenzidine colorimetric method in terms of measurement time,reading time,water sample temperature,and reagent dosage.And suggestions were made for online real-time monitoring of residual chlorine in water in China.
