Abstract: The synergic extraction of copper(II) with N-phenylbenzohydroxamic acid (PBHA) and tri-n-octyl phosphinoxide (TOPO) or tributyl phosphate (TBP) was investigated in chloroform. The synergic effect found in presence of neutral ligand is due to the formation of the adduct Cu(PBHA)2S in chloroform (S denotes TOPO or TBP). The synergic coefficients (SC) were determined which have higher value in presence of TOPO than TBP, since TOPO has the higher basicity then TBP.
