线性滴定中稳定常数测定方法比较

Comparison of the Methods of Determining Stability Constants in the Linear Titration

比较了计算稳定常数的各种方法：Ｇｏｒｄｅｎ法、ＭｏｎｔｅＣａｒｌｏ法，生成函数回归法、曲线模拟法、直接计算法和Ｓｃｈｗａｒｚｅｎｂａｃｈ法。分别验证了它们对单元酸、多元酸、混合酸等不同体系的实用性，获得了各种方法的最佳适用体系：Ｇｏｒｄｅｎ法适用于混合酸体系；ＭｏｎｔｅＣａｒｌｏ法适用于多元酸体系；生成函数回归法适用于交错中和体系；直接法适用于单元酸的未知体系。

The various methods of calculating the stability constants-Gorden method, Monte Carlo method, Bjerrumis formation function regression method,Curve modeling method, Direct computing method and Schwarzenbach method were compared. The practicability of these methods were proved by experimental results,respectively. And the suitable systems for various methods were obtained as follow:the Gorden method was suitable to the systems of mixture and unknown acids;the Monte Carlo method to the system of polybasic acids;the formation function method to the systems of interlock neutralisation;the direct computing method to the unknown systems of monobasic acids.
