摘要
本文将多元线性回归分析法应用于ｐＨ配位滴定，同时测定了与ＥＤＴＡ综合物稳定常数极为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。对十个合成样进行了测定，得到满意结果。
his article applies the method of multi-ple linear regression to pH complexometrictitration.It can determine simultaneously theconcentrations of metallic ions whose EDTAcomplexes have very simillar stability con-stants. The article has discussed the princi-ple of the method,regression equation andoptimum experimental conditions. Ten syn-thetic samples were determined and satisfac-tory results were obtained.
