A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

Rare Metals, EarlyView.
ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Efficient, Reversible Lead Adsorption in a Thiol‐Decorated Zirconium‐Metal–Organic Framework

Small, EarlyView.
A thiol‐decorated Zr‐MOF, Zr‐DMSA, efficiently captures Pb(II) from water via mixed S/O chelation enabled by flexible “dangling” ligands, as revealed by solid‐state NMR and pair distribution function analyses. Treatment with 1 M HCl fully reverses Pb binding, regenerating the material for up to 10 consecutive adsorption–desorption cycles.
