Abstract: In the paper, a succimide derivative was used as the surfactant, tri-n-octylamine as the mobile carrier, kerosene as the membrane solvent and Na2CO3 solution as the internal phase of the membrane to form a system of water-in-oil emulsified liquid membranes, in studying the extraction of uranium from sulfuric acid leach liquor. Factors affecting the stability of the liquid surfactant membranes and extraction efficiency of uranium were studied, and suitable technological conditions were determined. Experimental results showed the advantages of liquid membranes: rapid rate of uranium transport, high efficiency of extraction, high selectivity and good stability. The efficiency of uranium extraction was 99.4%.
