摘要:

我国的管网饮用水污染大部分属于有机物污染。针对低CODCr的检测精准问题,一方面须进行水样规范回流消解,另一方面采用长光程吸收光度技术结合自然对数吸光值技术,以有效扩展低浓度下的检测灵敏度。相关研究可为今后管网在线昼夜监测提供相应的技术准备。

Abstract:

Most of network drinking water pollution in China is of organic pollution. Aiming at the precision problem of low concentration CODCr monitoring,on the one hand the normalized reflux digestion of water sample should be implemented,and on the other hand,long-optical-path absorption spectrophotometry technology combining with the natural logarithm absorption value should be used,so as to effectively expand the monitoring sensitivity under low concentration condition. The relevant study and experiments can provide corresponding technical preparation for the day-and-night online monitoring on drinking water network in the future.

Key words: drinking water pollution, reflux digestion, drinking water of network
