Abstract:

According to the discussion on the principles and methods of permanganate index determination, the causes of making errors during the course of determination have been analyzed. The results show that the causes are in regard to potassium permanganate standard solution，heating time, acidity of reaction solution, titration velocity and so on.

Key words: permanganate index, heating time, potassium permanganate standard solution

摘要：

通过对高锰酸盐指数测定原理和方法的探讨,分析在高锰酸盐指数测定过程中产生误差的原因。结果表明,误差的产生与高锰酸钾标准溶液、加热时间、反应体系酸度、滴定速度等因素有关。

关键词: 高锰酸盐指数, 加热时间, 高锰酸钾标准溶液
