多元线性回归pH配位滴定法同时测定镍铅钴

The pH Complexometry of Multiple Linear Regression for Determing Ni, Pb,Co Simultaneously

将多元线性回归计算法应用于ｐＨ配位滴定法中，同时测定了其ＥＤＴＡ络合物稳定常数相近的金属离子浓度，讨论了方法原理、回归方程及最佳实验条件。对１０个合成样进行了测定，得到满意结果。

This article applies the method of multiple linear regression to pH complexometric titration. It determines metallic ions concentration simultaneously which is very similar to stable constant of EDTA complex compound. The article discusses the method principle,regression equation and optimum experimental condition. Ten synthetic samples were determined and satisfactory results have been obtained.
