| Abstract: | 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. |
