摘　　要：本文借5-Br-PADAP与CPB体系显色,用卡尔曼滤波-分光光度法同时测定钴镍铜锌镉五组分混合物,本方法用于合成试样、水、头发、指甲等环境样品分析,结果较好。Kalman filter used as a chemometric filter can filter out the mutual interferences.Based on the filtcr,a new spectrophotometric method was proposed for Simultaneous determination of Co,Ni.Cu,Zn and Cd with 5-Br-PADAP and CPB.The method was employed to analysis of synthetic and environmental Samples with good results.
