| Abstract Scope |
Rare Earth elements (REE) are highly requested by modern industry, being indispensable for construction of electric vehicles and environmentally friendly energy sources. Challenge in their production lies in their joint occurence and similar chemical properties. It can be answered by using solid phase extraction, applying highly selective nanostructured adsorbents. The latter are bearing organic ligands with high specific affinity to particular REE grafted on their surface via covalent bonding. A comparative study, demonstrating the ligand properties in relation to distinct REE and such conditions as concentration of solutions and pH. Recommendations have been elaborated for specific choice of ligands and adsorption-desorption conditions for improved separation of single REE. The results have been verified in separation of REE from complex leachates both by magnetic nano adsorbents and by mesoporous microparticles applied as a sorbent in High Performance Chelation Ion Chromatography (HPCIC). |
