Abstract
A method for generatingSc from a target solution, includes the following steps: a step of solid-liquid extraction comprising (a) the precipitation of a target solution comprising metal species with fluoride ions, the target solution comprising at leastSc,Ti, andSc and other metal impurities, whereby a solution comprising a precipitate made essentially ofSc is obtained, and (b) the filtration of the resulting solution and the recovering of the resulting filtrate comprising essentiallySc andTi; a step of solid-phase extraction chromatography comprising (c) the loading of the filtrate obtained by the previous step onto a preconditioned hydroxamate column, and (d) the elution of a hydrochloric acid solution through the preconditioned hydroxamate column, and a step of recoveringSc from the elution of the previous step.
