| Abstract Scope |
The separation and purification of rare earth elements (REEs) is of paramount importance to advanced technologies. The chemical similarity of these elements has required the development of new extraction techniques. Since the late 1950s and 60s synergistic effects of diluents and the addition aqueous complexing agents to suppress extraction have been applied to solvent extraction systems. This research applies the concept of adding complexing agents to a system of nano powders functionalized with trimesic acid adsorbent. Increased competition between REE complexes for the available extractant sites results in increased separation allowing for purities of individual REEs in a synthetic four element solution to be above 99% after two stages of adsorption. |
