Abstract

The extraction behaviour of Ni(II), Zn(II), Cd(II), Hg(II) and Pb(II) from aqueous solution, as function of pH, has been investigated with chloroform solutions of 1-phenyl-3-hydroxy-4-dodecyldithiocarboxylate-5-pyrazolone (HDTC-12) as extractant. In each case, the extracted species was found to be M(DTC-12)2 and the extraction constants were deduced by non-linear regression analysis. The results demonstrate that this ligand extracts selectively Hg(II) from Cd(II) as well as from Pb(II).
