Highly efficient and reusable Mg-Fe layered double hydroxides anchored in attapulgite for uranium uptake from wastewater.

Micro/nano interface adsorption is an effective strategy for separating uranium from aqueous solutions. However, their undesirable capture efficiency and poor cycling stability limit their practical application. In this study, we developed a clay-based micro-adsorbent constructed using attapulgite (ATP) and Mg-Fe layered double hydroxides (Mg-Fe LDHs) for uranium uptake from wastewater.
