同时求出浓度和离解常数的多元酸碱电位滴定法

Simultaneous Determination of Content and Conditional Dissociation Constant of Polybasic Acid or Polybasic Base by Potentiometric Titration

根据多元酸碱滴定计算通式 ,针对实际情况化简后 ,非线性回归同时求出浓度和条件离解常数。计算时 ,利用统计分析软件SPSS ,无需编程 ,结果满意。

On the basis of our mathematic models of the titration, the content and conditional dissociation constant may be determined by using nonlinear regression. The potentionmetric data processing is carried by using SPSS, the results are satisfactory.
