Abstract

The effect of trioctylammonium bis[(trifluoromethyl)sulfonyl]imide ionic liquid on the extraction of REE(III) with tetraoctyldiglycolamide from nitric acid solutions was studied. It was found that in the presence of an ionic liquid in the organic phase, the efficiency and selectivity of the extraction of metal ions from nitric acid solutions increases significantly. The influence of the acidity of the aqueous phase on the change in the distribution ratios of REE(III) was considered, and the stoichiometry of the extractable complexes was determined.
