摘要
影响高锰酸盐指数准确性的主要因素有:水浴加热时间、滴定时间、空白值、高锰酸钾溶液浓度、样品酸度等。通过实验分析了这五个因素对高锰酸盐指数测定的影响程度,这对高锰酸盐指数的准确测定具有指导意义。
The main factors affecting the accuracy of the determination of permanganate index,include water bath temperature, titration time,blank value,potassium permanganate concentration,acidity of sanlples. Through the tests of standard samples, the degree of affecting permanganate index by these 5 factors were investigated, which would be the guide meaning for the accurate determination of PID.
