Simple chemical method for the separation of rare earth metals
Abstract
A method is provided for separating mixtures of different rare earth metals using a ligand having a size-sensitive molecular aperture. The present invention meets the needs in the field by providing method of separating and purifying rare earth metals. The object of this invention is to separate and purify rare earth metals, e.g., the more valuable Dy away from Nd, in mixtures containing such metals using a simple chemical process without the need for countercurrent liquid-liquid separations.
