Summary:The effect of the ionic liquid {trioctylammonium bis[(trifluoromethyl)sulfonyl]imide} on the extraction of REE(III) with tetraoctyldiglycolamide from nitric acid solutions has been studied. It has been found that efficiency and selectivity of the metal ions extraction from nitric acid solutions are significantly increased in the presence of the ionic liquid in the organic phase. The influence of the aqueous phase acidity on the change in the distribution ratios of REE(III) has been considered, and stoichiometry of the extracted complexes has been elucidated.
