Abstract

AbstractPolythiosemicarbazides react with acqueous Cu+2 solutions with formation of polymeric chelates, for which the following structure is typical: The adsorption of Cu2+ by the polymer proceeds selectively and in preference to Fe3+, Zn2+, W6+, Al3+, Be2+, Cr3+, UO22+, Ni2+, V5+, Mo6+, Hf4+, Zr4+, Ta5+, Nb5+. Separations of these metals from Cu2+ are therefore possible.
