Size-dependent selective crystallization using an inorganic mixed-oxoanion system for lanthanide separation†
Abstract
A unique selective crystallization strategy based on an iodate–sulfate mixed-anion system has been developed for lanthanide separation. Periodic divergences in crystal formation energy enable simple Nd/Dy, La/Lu, Gd/Tb, La/Dy, and Nd/Lu separations through crystallization of the early lanthanides, giving rise to separation factors up to 123(5), 100(2), 2.4(2), 137(9), and 85(6), respectively.
