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 thesvstem 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.
