Abstract

The possibility of using new “heavy” diluents, carbonates of fluorinated alcohols, for extractive recovery and purification of uranium was examined. The physicochemical characteristics and extraction properties of the diluents were determined. Extraction mixtures based on tributyl phosphate and carbonates of fluorinated alcohols show promise for the uranium recovery from nitric acid process solutions owing to the following features: high distribution ratios of the target component, no third phase formation upon solvent loading, and insignificant extraction of nitric acid.
