缩短工业循环冷却水中总磷测定的时间

目前工业循环冷却水化学处理中大多采用磷系配方药剂，监控工业循环冷却水中总磷含量是水质分析一项非常重要的工作，本文通过多次实验测定，在保证分析准确的前提下，缩短消解时间及显色时间，缩短了工业循环冷却水中总磷测定的时间，在第一时间指导工艺，为工艺节能减排。

At present,the chemical treatment of industrial circulating cooling water was adopted in the most of phosphorous chemicals, determination of the content of total phosphorus from industrial circulating cooling water is a very important work of water quality analysis, in ensuring the ac- curacy of the analysis ,This paper take several experiments, for shortening digestion time and chromogenic time, and shortening the measuring time of content of total phosphorus from industrial circulating cooling water, for energy saving and emission reduction technology.
