dc.description.abstractThe suitability of dispersion liquid membranes (DLMs) to recover and purify uranium from simulated waste streams containing nitric acid, high uranium concentrations and radionuclide contaminants with tributyl phosphate (TBP) and ammonium carbonate ((NH4)2CO3) as stripping solution was investigated. The radionuclide surrogates were not extracted and complete uranium recovery was obtained from 15 g U L−1 solutions using a 1:4 ratio of 30% TBP in kerosene and 0.75 M (NH4)2CO3 dispersion. In addition, all the uranium in the stripping solution was precipitated. Consequently, DLM proved to be a promising solvent extraction contacting method for uranium recovery and purificationen_US
