dc.description.abstractA detailed NMR study on the possible interactions between a series of imidazolium based ionic liquids (1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl) amide, RmimTf2N, n = 4, 6, 8, 10), and compounds commonly applied in the solvent extraction and separation of 4f and 5f-ions as acidic chelating agents and neutral extractants is presented. The analytical techniques applied are 1H, 13C, 19F and 31P NMR spectra and NOESY experiments. Investigation of the types and strengths of the solvent-solute interactions is necessary for a better understanding of the chemical solubility, reactivity and selectivity, as ILs have a strong influence on the solvent extraction mechanism of metal ions. The goal of the scientific research is to gain insight on the role of ILs as a perspective efficient ``green`` medium in the solvent extraction processes. The experimental results show that no IL-ligand interactions occurred in chloroform solution independently on the length of the imidazolium alkyl chain or on the structure and acidity of the ligand.
