Effect of Didecylammonium Di-2-ethylhexyl Sulfosuccinate on the Extraction of Actinides and Lanthanides(III) from Nitric Acid Solutions with Tetraoctyldiglycolamide
摘要
Abstract
The efficiency of the extraction of lanthanide(III), americium(III), and thorium(IV) ions from nitric acid solutions with tetraoctyldiglycolamide significantly increases in the presence of an ionic liquid, didecylammonium di-2-ethylhexyl sulfosuccinate, in the organic phase. The effect of the aqueous phase acidity on the distribution ratios of the extracted elements was considered, and the stoichiometry of the extractable complexes was determined.
