Stepwise selective crystallization of Fe and Dy complexes from a Fe/Nd/Dy mixture: separation despite charge and solubility similarity

Abstract

Selective crystallization of charge-identical trenSal complexes enabled stepwise separation of Fe, Nd, and Dy. Remarkably, high selectivity emerged under controlled-base conditions, allowing separation even between species with similar solubilities. This study demonstrates a new approach for f/f and f/d metal separation based on controlled crystallization behavior.
