摘要
影响高锰酸盐指数测定准确性的主要因素是水浴加热时间、滴定时间和空白值,本文通过实验考察这三个因素对高锰酸盐指数测定的影响程度,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 Permanganate index determination are water bath calefaction time, titration time and blank value. Through experiments, affecting degree of the three factors to permanganate index is reviewed in the paper, which will guild the accurate measurement of PID.
