浅谈影响高锰酸盐指数准确度的若干因素

高锰酸盐指数是一个相对的条件性指标,其测定结果与标准溶液浓度、加热时间与温度、滴定条件、空白值等因素有关.全面总结分析了实际监测中各因素对CODMn测定的影响情况,并指出测定过程中应当注意的关键问题,对高锰酸盐指数的准确测定具有非常重要的意义.

Introduction to Several Factors Affect the Accuracy of Permanganate Index

Permanganate index is a conditional indicator, relative to the measurement results and the concentration of standard solution, heating time and temperature, and titration conditions, blank value and other factors. Comprehensive summary analysis of the actual monitoring of the effect of various factors on the determination of CODMn, and points out that attention should be paid to the key problems in process of permanganate index determination has very important significance.
