The optimum conditions for the pulse polarographic determination of Cu, Ti, Pb, Cd and Zn in air pollution particulates were investigated. The determination of these elements together by means of a single polarogram was achieved. Having experimented with various electrolytes at different pHs, it was concluded that the best medium was 0.02 M EDTA + 0.2 M sodium acetate solution at pH 2.
