The accurancy of determinations of total concentration of scaling cations Ca~(2+), Mg~(2+), Ba~(2+), and Sr~(2+) and of concentration of single cation Ba~(2+) or Sr~(2+) (by) EDTA-complexometric titration is studied experimentally.
对络合滴定法测定混合成垢阳离子Ca2+、Mg2+、Ba2+、Sr2+总浓度和单一成垢阳离子Ba2+或Sr2+浓度所得结果的准确度进行了实验考察。
