Functionalized Mesoporous Carbon Fibers for Effective Recovery of Rare Earth Elements from the Acidic Extract of End-of-Life Magnet Scrap
Abstract
To develop functionalized mesoporous carbon fiber (MCF) materials that can be used in solid-liquid separation systems for effective extraction, concentration, and purification of REEs from electronic and industrial wastes. Specific research objectives: To develop ligand-assisted extraction technology of REEs from NdFeB powder as a model system for magnet scrap. To develop MCF materials with tunable pore size, pore structure, and surface functionalities using diblock copolymer templates. To develop new organic-ligand functionalized MCF materials using post-synthesis methods. Target ligands include diglycolamide (DGA), and diethylenetriaminepentaacetic acid (DTPA).To elucidate the molecular, nano, and micro scale interactions and binding mechanisms of REEs with organic ligands and MCF materials by using advanced spectroscopic characterizations.
