Abstract

Abstract : Magnetic core–shell microspheres were developed to extract rare earth elements (REEs) from aqueous and brine solutions with up to 99.99% removal efficiency. The shell, composed of a thermally and chemically stable functionalized metal–organic framework (MOF), is grown over a synthesized Fe3 O4 magnetic core (magnetite@MOF). Abstract : Magnetic core–shell microspheres were developed to extract rare earth elements (REEs) from aqueous and brine solutions with up to 99.99% removal efficiency. The shell, composed of a thermally and chemically stable functionalized metal–organic framework (MOF), is grown over a synthesized Fe3 O4 magnetic core (magnetite@MOF). The composite particles can be removed from the mixture under an applied magnetic field, offering a practical, and efficient REE-removal process.
