摘要： 提出了离子选择电极电位法中用于计算结果的三参数拟合法。该法可用于各种类型的电位滴定。本法的优点是精度较高,同时可确定Cx,E′o、S。法特别适用于自动滴定分析。

Abstract: A new method for evaluation of results of potentiometric titrations is proposed. This method is based on the three-parametric curve fitting and has been verified by experiments and by theoretical values and literature data. The results obtained indicate that it can be used for all reaction types of titrations. One advantage of the present method is that it allows simultanous calculation of E'0,S and Cx with high precision. The method is particularly suitable for the full automatic potentiometric titration systems.
