电位滴定法测定工业循环水中总硬度

Determination of total hardness in industrial circulating water by potential titration

水中总硬度测定采用EDTA络合电位滴定法。本文从电位滴定法原理、操作流程、参数设置及精准度等方面做了阐述,通过与化学分析方法对比,两者没有明显差异。

The potential titration method of EDTA complex titration is used to determine the total hardness in water.This paper expounds the principle,operation process,parameter setting and accuracy of potentiometric titration.By comparing with chemical analysis methods,there is no obvious difference between the two.
