Extaction of uranium by HEHEHP with liquid membranes

Du Huifang; Sheng Jiawei; Zhou Zuming(Department of Nuclear Science)  
An emulsified liquid membrane system has been used for extraction of uranium. The system includes a surfactant (a succimide derivative), a carrier (HEHEHP), a solvent (kerosene and liquid paraffin oil),and the internal phase(1.44 mol. L-1 H2SO4 solution). The stability of the emulsified liquid membrane and the factors affecting the extraction efficiency of uranium such as temperature, uranium concentration, sulfuric group concentration, pH value of outer water phase and the ratios of emulsion to water have been studied. Experimental results show that the efficiency of uranium extraction may arrive 100% under an appropriate condition. Liquid membrane method is an efficient, fast and economical method for extraction of uranium.
