摘要
本文将微分电位溶出分析法用于络合反应研究,提出微分电位溶出滴定法;推导了用此法测定金属有机络合物及其条件生成常数的理论公式,并用镉与EDTA的络合反应进行了实验验证,获得满意结果。
The method of differential potentiometric stripping titration has been proposed. Thetheoritical equations for titration curve used to determine metal-organic complex compoundsand its conditional formation constant have been derived and testified by experiments forCd-EDTA complex. The results were satisfactory.
