he transfer of H+ and Li+ ions through the water - 1,2 dichloroethane interface in the presence of 1,10-phenenthroline is studied by cyclic voltammetry. These ions compete for the phenanthroline in the organic phase; the pH and the concentration of the ligand relative to that of the cation determine which predominates in the transfer. It is concluded that the transfer of H+ mediated by phenanthroline occurs via a direct mechanism, whereas "facilitated" transfer is operative in the case of Li+.
