Abstract: Copper(II) is separated quantitatively from its binary mixtures with Cr(lll), Mn(II), Co(II), Ni(II), Zn(II), Cd(ll), Hg(ll), Ag(l), Pb(II) and Mg(II) using synergic combinations of triphenylphosphine oxide (or 2,4-pentanedione) with 8-hydroxyquinoline. The anions tested, viz., Cl-, NO, CH3COO- and SO do not interfere; Fe(III), however, interferes in the extraction of Cu(ll). The nature of species, their extraction and stability constants are calculated from the metal distribution data using linear regression analysis. The nature of extracted species of Cu(II) with 2,4-pentanedione alone is also reinvestigated.
