Abstract: The compound 2-QADNm can form red complexes with caamium(II), zinc(II) and copper(II). The simultaneous determination of cadmium, zinc and copper with Kalman Filter is described in this paper, the proposed method was applied to a two-component system for determining cadmium and copper,and a three-component system for determining cadmium, zinc and copper.

Key words: Simultaneous Spectrophotometric determination, Kaiman Filter, Zinc, Copper
