<p>A separation and up-concentration of mutually replaceable components from partially miscible phases is realized by a successive contacting of a transfer phase with concentration phases containing the easiest replaceable component. After exhausting of the components to be separated and after a pre-treatment including bonding of the components from their source, the transfer phase is used again as the new input transfer phase. The transfer phase containing salts of unsaturated fatty acids and metals, transition elements, ammonium and/or amines as the components to be separated, is successively contacted with acidified water concentration solutions in order to separate and up-concentrate groups or single components. Water solution of water-soluble metals salts, transition elements, ammonium and/or amines may be used as the transfer phase the concentration phases are formed by an unsaturated fatty acid. The components are separated in the concentration phases according to their electronegativity values.</p> |
