摘　　要：本文运用卡尔曼滤波(KF)递推算法,以2-(5-溴-吡啶偶氮)-5-二乙氨基苯酚(5-Br-PADAP),溴化十六烷基吡啶(CPB)同时测定了五组分混合物:Co、Ni、Cu、Zn和Cd中各元素百分含量,合成样分析结果良好。用模型数据可测百分含量相差50倍的离子混合物。Kalman filter(KF) used as a chemometrics filter can filter out the interferences from each other. A spectrophotometric method based on KF is described for simultaneous determination of Co,Ni,Cu,Zn and Cd with 2-(5-bromo-2-pyridylazo)-5-dimethylamino phenol (5-Br-PADAP)and cetylpyridinium bromide(CPB).The procedure is accurate and selective. The method was applied to the analysis of synthetic samples with satisfactory results.
