中控分析氯酸盐工作液中硫酸根的研究

STUDY ON THE MID-CONTROL ANALYSIS OF SULFATE RADICAL IN THE WORKING LIQUOR FROM CHLORATE.

硫酸根的分析方法有重量法、络合返滴定法、目视比浊法，还有分光光度法等，这些方法无法直接用于中间控制分析氯酸盐工作液中硫酸根的含量，只能经过实验重新研究确定。现我们已研究出可直接用于中间控制分析氯酸盐工作液中的硫酸根的分析方法：掩蔽—分光光度法。

The weight method,back complexometric titration method,the visual ratio-turbid way and the spectrophoto metric method etc.are used to analyse the sulfate radical,but these methods can not be used directly to analyse the sulfate radical content in the working liquor from the chlorate in the mid-control procedure.Now,through the test,the covering spectro-photometric method is given,which can be directly used for the mid-control analysis.
