Improving the Robustness of Trivalent Actinides/Lanthanides Separation by Bis(2,4,4-trimethylpentyl)dithiophosphinic Acid: Batch Extraction and Process Demonstration

Separation studies during the past decades have demonstrated that ligands with “soft” donor atoms (e.g., N and S, relative to O) show greater affinity to An(III) over Ln(III) in solvent extraction....
