It is shown that the imposition of a constant electric field makes it possible to carry out the transfer of PdCl42- ions through liquid membranes containing tri-n-octylammonium and trialkylbenzylammonium chlorides into dilute solutions of hydrochloric, sulfuric, perchloric, nitric acids and into water.The effect of the composition of aqueous and organic solutions, the current density of electrodialysis, the intensity of stirring and the thickness of the liquid membrane on the rate of transmembrane transfer of palladium (II) has been studied. It was found that the flux of PdCl42- ions increases with an increase in the initial metal concentration and current density, whereas an increase in the concentration of hydrochloric acid in the feed solution and the content of carriers in the organic membrane negatively affects the rate of palladium (II) extraction. It is shown that the composition of the stripping solution, the thickness of the liquid membrane and the rate of stirring of the solutions do not have a significant effect on the rate of membrane extraction. The maximum flux of palladium (II) through the liquid membrane is 120 μmol · m-2 · s-1. The processes of membrane extraction of palladium (II) from binary hydrochloric mixtures containing macroimpurities of base metals have been studied, and the conditions for selective extraction have been determined. The obtained maximum separation coefficients of palladium (II) ions from nickel (II), iron (III), copper (II) ions are 5000, 770, 22, respectively.
