Advancing Selective Extraction: A Novel Approach for Scandium, Thorium, and Uranium Ion Capture.

ABSTRACT: The potential use of thorium (Th) and uranium (U) as nuclear fuels underscores the importance of developing materials for their sustainable recovery. The production of Th and U requires the separation of these elements from rare-earth elements (REEs) as they often coexist in various feedstocks. Equally crucial is efficiently isolating scandium (Sc) from REEs, considering its high-value status and pivotal role in advanced alloy technologies. This study introduces a new selective ligand-functionalized silica sorbent for extracting Sc, other REEs, Th, and U from solutions with varying pH and elemental compositions. The functionalized sorbent exhibits exceptional selectivity for Sc ions at pH 4 across solutions containing 3-20 elements. It also shows excellent selectivity for Th at pH 2 in 18-
