Adsorptive membranes for rare earth element recovery are reviewed, showing that coordination and electrostatic interactions—along with surface complexation and ion exchange—govern adsorption performance and regeneration.
- Why it matters: Conventional REE production raises resource security and environmental concerns, motivating recovery from secondary aqueous streams where continuous separation and reusability are needed.
- What they did: The review synthesizes membrane engineering strategies—ion-imprinted, ligand-functionalized, metal-organic framework-based, biopolymer-based, and carbonaceous systems—linking adsorption equilibrium/kinetics/thermodynamics and pH/competing ions to performance, supported by spectroscopy and density functional theory.
- The result: It identifies limits including insufficient selectivity in complex matrices, inconsistent reporting, limited continuous-flow validation, and inadequate long-term regeneration studies, guiding future optimization for saline streams and desalination concentrates.
