| Abstract Scope |
In recycling, the separation of REE from LTM represents a principal challenge. While iron can easily be separated by controlled increase in pH, separation of Co, Ni and Cu requires application of advanced approaches including fractional crystallization, solvent extraction or use of solid adsorbents. The latter can be made selective by grafting of specific ligands reacting in a different manner with targeted classes of metal cations. Applying molecular model approach combined with advanced spectroscopic measurements we were able to visualize principally different reaction pathways between REE and LTM in uptake by poly-amino ligands. The observed differences permit to tailor adsorbents with pronounced selectivity on both adsorption and desorption of the cations of interest. |
