The extraction of uranium(VI) through a W/O/W liquid membrane containing DEHPA was studied in the counter transport system. The optimum stable conditions of W/O emulsion were determined; the optimum concentrations of surfactant span 80 and paraffine oil were 2 Vol.% and 50 Vol.%, respectively. The extraction results showed that more than 95% of uranium(VI) was extracted during 10 minutes when the carrier concentration was 4 Vol.%, internal aqueous phase; 1N-H₂SO₄solution, external aqueous phase; pH 2 and mixing speed; 350 rpm.
