影响水中高锰酸盐指数准确检测的因素

Factors Affecting Detection of Water Permanganate Index Accurately

由于高锰酸盐指数测定的影响因素较多，其结果随机变化也较大，通过查阅大量文献，汇总细化操作过程，试图减少实验环节各因素对结果的影响，提高质控效果。

There are many factors on determination of permanganate index and the results changes a lot randomly. The detection process were summarized and refined by referring a large number of papers in order to avoid the impacts from various factors during the experimental part and improve quality control.
