Separation of zinc(II), cadmium(II) and mercury by solvent extraction using thiocarbohydrazide and the complexing agent
The extraction behaviour is reported of zinc(II), cadmium(II) and mercury(II) complexes of thiocarbohydrazide in benzene, chloroform, carbon tetrachloride, di-isopropyl ether, ethyl acetate, amyl acetate, and amyl alcohol. The separation of the three elements has been achieved by the use of various masking agents, as well as by making use of the effect ofpH on their extractability.
