The Use of Tri- n -octylamine for the Separation of Vanadium(V) from Acidic Sulfate Uranium Leach Liquors

· Separation Science
Extraction of vanadium(V) from acidic sulfate solutions by a mixture of tri-n-oxtylamine and tributylphosphate (used as modifier) dissolved in kerosene has been studied. The distribution coefficient of vanadium(V) increases with an increase in pH and vanadium(V) concentration. The presence of iron(III) in aqueous solution does not have any appreciable effect, while large amounts of sulfate ion depress the distribution coefficient. Uranium(VI) has a distribution different from vanadium(V). Based upon these results, a scheme for the separation of vanadium(V) from uranium leach liquors has been made and checked experimentally.
