Solvent Extraction of Uranium with Acetylacetone and Tri-n-Butyl Phosphate in n-Dodecane

[摘要] Uranium (¥µ) was extracted from dilute aqueous solutions of uranyl nitrate with acetylacetone and tri-n-butyl phosphate in n-dodecane. Synergistic effect was observed with the mixed reagents above pH 1. The species extracted are the 1:2:1 and the 1:2:2 uranyl-AA-TBP complexes. The extraction constants for these reactions have been determined.
