Abstract

Features of interphase distribution of scandium chloride in the systems containing tributyl phosphate and molecular iodine have been analyzed. Significant electrolytic dissociation of the formed complex scandium chloride with tributyl phosphate and iodine in the organic phase (almost complete at tributyl phosphate concentration 80–100%) has been observed. The increase in electroconductivity of the solutions of scandium chloride has been most prominent at the ratio of scandium chloride and iodine corresponding to the formation of monosolvate. Accounting for electrolytic dissociation in the organic phase allowed the description of the interphase extraction of scandium chloride in the studied systems.
