Abstract

The separation of trivalent actinides from lanthanides is a key challenge in the advanced nuclear fuel cycle and is also a global problem due to the extreme similarity of the charge density, ionic radius, and physicochemical properties of trivalent actinides and lanthanides. This paper reviewed the research and application progress in the separation of trivalent actinides from lanthanides using dithiophosphinic acids in the last two decades, mainly focusing on the work by Tsinghua University. Moreover, this paper gives prospective views on future trends in this area.
