The synergistic extraction of some divalent cations (Cd, Cu, Mn and Zn) in chloroform, with 3-phenyl-4-benzoylisox- azol-5-one (HPBI) in the presence of various synergistic agents: trioctylphosphine oxide (TOPO), octyl(phenyl)(N,N-diisobutyl- carbamoylmethyl)phosphine oxide (CMPO) and bis(diphenylphosphinyl)methane (BDPPM) has been studied. It is compared with the extraction in toluene. Due to various factors (e.g. extractant-diluent or extractant-synergist interactions), the stoichiom etry of the extracted species, the selectivity and the magnitude of the synergism depend on the diluent and on the synergist. In chloro - form, the extraction with HPBI and TOPO follows the order Cu > Zn > Mn > Cd (Mn > Zn in toluene). In chloroform, the synergistic extraction of cadmium follows the order BDPPM > CMPO > TOPO (TOPO > CMPO in toluene). The formation constants of Cd(PBI)+ and Cd(PBI)2 in aqueous medium have been evaluated.
