摘要：

The isolation of minor uranium concentration from thorium matrix in HCl medium was investigated using liquid emulsion membrane (LEM) containing TOPO as carrier, Span 80 as surfactant and sodium citrate as stripping agent. The factors affecting the stability of the LEM were investigated. Different parameters affecting the permeation process were also studied. The results obtained showed that, under certain conditions it is possible to isolate ca. 98% of U(VI) (120 ppm) in 1.0M HCl solution containing Th (1000 ppm). The isolated U was found to be contaminated with less than 3% of Th.
