Abstract

Hexafluoroacetylacetone can react in solvent-minimal routes to effect separation of lanthanides from uranium matrices without any pre-preparation, and provides a path to drastically simplify the separations process and limits the potential for contamination and waste formation due to extensive handling, while increasing the rapidity of separation and isolation of target elements. Lanthanum and uranium can be separated, from a mixture of their oxides, with high selectivity. The choice of solvent was the major variable affecting the distribution coefficients of each component.
