自动电位滴定法测定水中总硬度的应用研究

Study on the Application of the Determination of Total Hardness in the Water with Antomatic Potentiometric Titration

该文采用自动电位滴定代替手动滴定,通过电位突变指示终点来测定地下水中的总硬度,并与手动滴定进行了比对实验。结果表明,自动电位滴定法具有准确性高、精密度好、干扰小、大大节省劳动力等优点,不失为一种好的水中硬度的测定方法。

In this paper, the total hardness in groundwater was determined by automatic potentiometric titration instead of manual titration and it indicated the end of the mutation by potential. And it was compared with the manual titration experiments, the results show that it is a good method of determination of the total hardness which has high accuracy, better precision, small interfering, saving labor, etc.
