摘要：

Uranium(VI) in the aqueous solution of (3 - 6) M (1 M = 1 mol dm(-3)) HNO3 + 3 M LiNO3 was extracted into supercritical CO2 fluid containing 3 vol% of tri-n-butylphosphate (TBP) at 60 degrees C and (1.5 - 3.5) x 10(7) Pa. Rapid and complete removal of CO2 medium from the extract was attained by gasification of CO2 at atmospheric temperature and pressure.
