Description

Extraction of uranium by organic solvents employing a novel synergistic combination of organo-phosphorus reagents is reported in this paper. In particular, the solvent mixture of Tris Ethyl Hexyl Phosphate (TEP) with Tri Octyl Phosphine Oxide (TOPO). Results on extraction from crude phosphoric acid are reported. Stripping of uranium from the organic phase was achieved with concentrated phosphoric acid, hydrochloric acid, nitric acid, ammonium carbonate, sodium carbonate, sodium hydroxide and sodium acetate.
