主成分络合电势滴定法及其应用的研究

Simultaneous Multicomponent Determination of Principal Component Analysis and Compled Potential Titrimetry(PCAC PT)

系统研究了化学计量学方法在滴定分析中的应用，将主成分回归与单点络合电势滴定法相结合同时测定了三元或四元多组分混合试样中各组分金属离子混合物，探讨了方法原理及矩阵求解，确定了主成分常数矩阵，结果良好．

Systematic researches are made on chemometrics in titration.Principal component analysis(PCA)method is employed to single-point compled potential titrimetry(CPT).The developed PCA-CPT technique is then used for simultaneous determination of each component metal ion in three-component or four-component mixture samples.The method and principle of the techenique were approached as well as the matixes ware found the solution.The principal componet constant matrix is determined.Satisfactory analytical results are obtained.
