ZIF-67-Embedded Polyacrylamide/Sodium Alginate/Polyacrylic Acid Hydrogel for Efficient and Selective Uranium Extraction

ligands of ZIF-67 are the primary adsorption mechanism of U(VI) adsorption. This work aims to design a hydrogel adsorbent with a porous structure and multifunctional groups, providing an important strategy for developing high-performance materials for seawater uranium extraction.
