SELECTIVE SEPARATION OF SAMARIUM FROM LIGHT RARE EARTH ELEMENTS via pH-CONTROLLED SOLVENT EXTRACTION

Abstract
Rare Earth Elements (REEs) are essential for advanced technologies due to their unique properties. This study presents a pH-controlled solvent extraction method to separate Samarium (Sm) from light REEs simulating Beylikova REE leaching liquid. The process, utilizing 0.75 M DEHPA in kerosene, showed that Sm achieved a 59% extraction efficiency at pH 0.5, significantly higher than La, Pr, and Nd. This pH optimization enhances the sustainability and efficiency of REE extraction, promoting the effective utilization of Turkey's REE resources and domestic technologies.
