摘要

研究了使用新的“重”稀释剂氟化醇碳酸盐进行铀的萃取回收和提纯的可能性。测定了稀释剂的理化性质和萃取性能。基于磷酸三丁酯和氟化醇碳酸盐的萃取混合物显示出从硝酸工艺溶液中回收铀的前景，因为它具有以下特点：目标组分的高分布比，在溶剂装载时不形成第三相，并且硝酸的萃取量很小。

Properties of the Extraction System Based on Tributyl Phosphate and Carbonates of Fluorinated Alcohols as Applied to Uranium Recovery from Nitric Acid Process Solutions

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.
