摘要：
The complexes formed from uranyl salts and tri-n-butyl phosphate (TBP) in ionic liquids (ILs) were studied by spectroscopic methods. [UO2(TBP)4]2+ is formed from UO2(ClO4)2·xH2O with excess of TBP in ILs. The coordination number of uranyl in [UO2(TBP)4]2+ is determined as 4 by ATR–FTIR study. In [Bmim][NTf2], though TBP cannot replace the NO3− coordinated to uranyl, TBP/[Bmim][NTf2] can extract “nitrate-free” uranyl complex from diluted HNO3 medium and the extracted complex is converted into [UO2(TBP)4]2+ after drying. The formation of [UO2(TBP)4]2+ provides spectroscopic evidence for the cation-exchange mechanism of uranyl extraction by TBP/[Bmim][NTf2] from diluted HNO3 medium.
