紫外－可见光分光光度法测定水中高锰酸盐指数研究

摘要

水质监测高锰酸盐指数有三种方法：通量计算法、区域实测法、浓度递增法。紫外－可见光分光光度法是实测水中高锰酸盐指数的常见方法。本文通过模拟实验的方法研究了紫外－可见光分光光度法测定水中高锰酸盐指数的影响因素，总结了此方法测定高锰酸盐指数的最优条件。%There are three ways to monitor permanganate index in water,namely flux calculation method,measure-ment method,progressive increasing concentration method.Ultraviolet visible spectrophotometry is a common meas-urement method to test permanganate index as well.The simulation method was used to identify the factors affecting UV -visible light spectrophotometric method for the determination of permanganate index in water.The optimal experimental conditions were summarized in the end.
