碱性法测定高锰酸盐指数的探讨

Study on the determination of permanganate index by alkaline method

高锰酸盐指数是地表水分析中的常规项目。由于测定影响的因素多,因此,测定结果的精密度和准确度不好控制,探讨酸度、浓度、温度、测定结果的精密度和准确度,为准确分析该指数提供参考。

The permanganate index is a common item in surface water analysis.As there are many factors influencing the measurement,the precision and accuracy of the measurement results are not well controlled,and the precision and accuracy of the measurement results can be used as a reference to explore the acidity,concentration,temperature,precision and accuracy of the measurement results.
