Abstract: The deep purifing system is made up from 4 kinds of foam plastics column containing respectively active MnO2, NaBiO3, cadmium(zinc) diethylaminothiocarbamate and dimethylglyoxime in series. When a solution of zinc or cadmium sulfate flows through the svstem the content of Fe2+, Cr3+, Mn2+, Cu2+, Pb2+, Co2+ and Ni2+ in it can be decreased rapidly and simply from 1～10μg/g to less than 0.1～0.5μg/g.

Key words: chromatography, foam plastics, zinc sulfate, cadmium sulfate
