浅析酸性法测定高锰酸盐指数的影响因素

Analysis of Factors Influencing Determination of Permanganate Index by Acid Method

高锰酸盐指数是饮用水、地下水和地表水水质监测分析的常规项目,文章对溶液酸度、高锰酸钾浓度及加热时间三个影响因素进行了探讨。实验结果表明,酸性法测定高锰酸盐指数与溶液酸度、高锰酸钾溶液浓度及加热时间密切相关。

The permanganate index is a routine project for the monitoring and analysis of drinking water, groundwater and surface water quality. Three factors affecting the solution acidity, potassium per-manganate concentration and heating time are discussed. The experimental results show that the deter-mination of acid permanganate index with the solution acidity, potassium permanganate solution concen-tration and heating time are closely related.
