Abstract
Milligram amounts of uranium dioxide can be quantitatively dissolved in sup ercritical carbon dioxide containing a complex of tri-n-butyl phosphate (TB P) with nitric acid and separated from thorium(IV). The quantitative dissol ution of milligram amounts of solid uranium trioxide in supercritical carbo n dioxide containing thenoyltrifluoroacetone (TTA) and TBP was performed us ing ultrasonication. The separation of uranium(VI) and cerium(IV) in the te st system was demonstrated.
