acidic potassium permanganate method的意思|示意

The uncertainty of measurement was evaluated for the determination of permanganate index of water by the method of GB 11892-1989, the acidic potassium permanganate method.

对GB 11892 - 1989《水质高锰酸盐指数的测定》中酸性高锰酸钾氧化法测定水中高锰酸盐指数的测量不确定度进行了评定。

This article discusses the acidic potassium permanganate method of permanganate index from the following aspects: heating time, titrate temperature and titrate speed, end point of titration.

前言：文章对高锰酸盐指数加热时间、滴定温度、速度、滴定终点的控制进行了探讨。
