Simultaneous Determination of Cadium, Nickel, Zinc, Cobalt, Iron and Mangnese by Kalman Filter Polarography

She Zhenbao , Wang Zhenghuan (Changchun Geological Colleger Changchun 130026)  
The overlapping waves of polarography were resolved by using Kalman filter, and some elements (Cd,Ni,Zn, Co,Fe, Mn) in 0. 1 mol/L potassium chloride, 0.3% sodium sulfite, 0.5% sodium salicylate and ammonium buffer solution were simultaneously determined. The method is simple, fast and accurate. This is a good method suitable for determining microelements in copper alloy.
