The distribution of uranium(IV) and uranium(VI) between phosphoric acid solution and mono-(2-ethylhexyl) phosphoric acid (H/sub 2/MEHP)-trioctyl phosphine oxide (TOPO), and mono-(2-ethylhexyl) phosphoric acid-dibutyl butyl phosphonate (DBBP) in kerosene diluent has been investigated. The effects of extractant composition, phosphoric acid concentration, temperature, uranium concentration, and shaking time on the uranium extraction have been examined. Reductive extraction and oxidative stripping processes for the separation and concentration of uranium from phosphoric acid solution with synergic systems of H/sub 2/MEHP-TOPO and H/sub 2/MEHP-DBBP are proposed and discussed.
