酸性法测定地表水高锰酸盐指数关键步骤的探讨

Discussion on key determination procedure of surface water permanganate index by acid process

高锰酸盐指数是评价地表水环境质量的重要指标,酸性法是测定地表水高锰酸盐指数的常用方法。本文研究了pH为1~2的水样是否需调至中性以及如何正确排除浊度对测定的干扰,为合理评价地表水水质提出了解决办法。

Permanganate index was the key evaluation index of the quality of surface water environment.And acid process was the common method of determination surface water permanganate index.In this paper,we have studied whether the water sample with pH 1~2 should be adjusted to neutral,and how to remove the interference of turbidity to the determination.The settlement about reasonable evaluation surface water quality was provided.
