Description
Summary:The novel ligand N,N,N′′′′ , N′′′′ -tetrabutyl- N′′′ , N′′′ -( N ″, N ″-diethyl)-ethidene bisdiglycolamide (TBEE-BisDGA) and other eight analogous extractants have been synthesized and characterized by NMR and HRMS. The solvent extraction of Th 4+ , UO 2 2+ and Eu 3+ from nitric acid solution using the above BisDGA extractants was investigated in 1-dodecanol at 30 ± 1 °C. The extractants exhibited higher affinity toward Th 4+ than UO 2 2+ and Eu 3+ in the present system. The maximum value of separation factor SF Th(IV)/U(VI) and SF Th(IV)/Eu(III) is 78.5 and 53.3 respectively for TBEE-BisDGA, 88.1 and 69.5 respectively in the case of TB i - PE-BisDGA at 3 M HNO 3 solution.
