摘要：
The separation of uranium from synthetic Hanford site groundwater by liquid-liquid extraction and by supported liquid membranes (SLM) waa studied. Bis(2,4,4-trimethylpentyl) phosphinic acid, H[DTMPeP], contained in the commercial extractant Cyanex 272, was selected for the membrane carrier because of its selectivity for uranium over calcium and magnesium. n-Dodecane was used as diluent and polypropylene membranea were used aa the support. A water soluble complexing agent, 1-hydroxyethane-1,1—dinheaohnnic acid. HEDPA. was used aa atripping agent. © 1990, Taylor & Francis Group, LLC. All rights reserved.
