|Title:||Organophosphorus reagents as extractants: Part 2-Synergic effect of triphenylphosphine oxide on the extraction of Co(II)/Zn(II) from binary mixtures with Cr(III), Ag(I), Hg(II), Mg(II) or Al(III) using 8-hydroxyquinoline|

Suitable combinations of 8-hydroxyquinoline (HQ) and triphenylphosphine oxide(Ph3PO) show synergism of 10-12% in the extraction of Co(II) and Zn(II) compared to the use of HQ alone. At the synergic points, Co(II)/Zn(II) are separated from their binary mixtures with Cr(III), Ag(I), Hg(II), Mg(II) or Al(III). The recovery is 95-97% and the nature of the species is CoQ2(Ph3PO) and ZnQ2(Ph3PO)2 respectively for Co(II) and Zn(II). The effects of pH of solutions, dilution of the phases and various anions are studied.
