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

open access: yesRare 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

open access: yesSmall, 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.

Measures to Ensure That Social Workers Render Holistic Family Reunification Services: A South African Perspective

open access: yesChildren &Society, EarlyView.
ABSTRACT Placement of children in alternative care is supposed to be a temporary arrangement while social workers address issues that led to the removal of a child from the care of the family. However, in the rendering of family reunification services (FRS), social workers encounter numerous challenges that hinder their ability and capacity to render ...
