Extraction of the trivalent transplutonium actinides americium through einsteinium by the sulfur donor Cyanex 301

Abstract

When extracting metals with the sulfur donor ligand, Cyanex 301 (bis(2,4,4-trimethylpentyl)dithiophosphinic acid), a transition in the coordination mode of extracted complexes has been observed between Eu and Gd, but not within the actinide series.
