用因子分析和卡尔曼滤波进行卟啉体系的多组份分析

ANALYSIS OF MULTICOMPONENT WITH PROPHRIN SYSTEM USING FACTOR ANALYSIS AND KALMAN FILTER

本文应用因子分析和卡尔曼滤波，以四（４一对羟基苯基）卟啉为显色剂，对铅、锌、镉三组分混合物进行同时分光光度测定，测定结果符合痕量分析要求。

Using factor analysis and Kalman filter(KF)method,the tricomponent mixtureof Pb、Zn and Cd is determined with simultanous spectrometry the meso-tetra(p-hydroxyphenyl)porphyrin as a colour agent. The resuIts of determination are in accord with re-quirement of microanalysis.
