Project description
The framework of this research project lies within the scope of the circular economy, focusing on addressing the present-day challenges in procuring critical raw materials such as rare earth elements (REE) that instigates progressions towards the establishment of a cleaner and greener environment. The primary intent of the exhaustive experimental study was to synthesize high-performance adsorbents that can enable sufficient REE recovery from dilute aqueous solutions in real wastewater conditions. Extensive analyses were conducted to identify adsorbents with enhanced REE selectivity, exploring further into the interactions of heavy and light REEs with the host matrix. Among the REEs, more emphasis was shed on Scandium (Sc) being an element of great significance that can serve as the spearhead for future technology. Finally, the REE-selective materials are then tested in a novel electrodeionization system for the separation and concentration of REE from mining effluents.
