Ionic Liquid as a N,O-Donor Ligand-Based Extraction System Modifier: Establishing the Mechanism of Am(III)-Selectivity Increasing

“…27 However, ionic liquids can be synergistic additives rather than bulk diluents for separation of f-elements. 26,34−38 We hypothesize that the combination of N,O-donor extractants with a hydrophobic anion NTf 2 − (bis[(trifluoromethyl) sulfonyl]imide) 39,40 should improve the extraction parameters of the system for the separation of An(III) and Ln(III). 41,42 In the present work, we aimed to explore the potential modification of the extraction system based on fluorinated solvents F-3 and L by adding the ionic liquid C 4 mimNTf 2 (IL) into the organic phase (Figure 1).…”
