报告摘要:Rare Earth Elements (REEs) have unique physicochemical properties that make them essential elements in many high-tech components, such as electric vehicle, power generator, MRI, screen display, hydride batteries and energy storage. Traditional separation methods like centrifugation and filtration are usually labor-consumptive, uneconomical and environmental pollutant. Magnetic separation nanotechnology developed in our lab is an upcoming technique for REE recycling. Magnetic nanosorbents exhibit special superiority due to convenient separation by an external magnetic field.  Advantages of magnetic nanosorbents are low inventory utilization of nanosorbents, enhanced sorption efficiency, high selectivity, and low production of secondary waste. This talk presents the study on our lab-made magnetic nanosorbents – double coated magnetic nanoparticles (dMNP) conjugated with diethylene triamine pentaacetic acid (DTPA) and their potential to be used as effective sorbents to recycle trivalent lanthanides from aqueous solutions. The REE sorption results show that the magnetic nanosorbents possess a high stability, fast kinetics, and high sorption efficiency in harsh environments. The metal sorption on the nanosorbents is reversible so that the metal-loaded dMNP-DTPA can be effectively regenerated by the dilute acids. The nanosorbents can be reused for more than 15 sorption/desorption cycles, which helps to offset the synthesis cost and makes this technique cost-effective in REE recycling.
