酸性法高锰酸盐指数测定的影响因素研究

Research of influencing factors on the accuracy of permanganate index determination by acid method

影响高锰酸盐指数测定准确性的主要因素是酸度、水浴加热时间、高锰酸钾浓度和滴定时间等。本文通过对环境标准样品的测定,考察酸度、高锰酸钾标准溶液的浓度、水浴加热时间、滴定时间几个主要因素对高锰酸盐指数测定准确性的影响程度。

The main factors affecting the accuracy of permanganate index determination are acidity,water bath heating time,potassium permanganate concentration and titration time.In this paper,through the determination of environmental standard samples,the influence of acidity,concentration of potassium permanganate standard solution,heating time of water bath and titration time on the accuracy of permanganate index determination was investigated.
