Phytic Acid Functionalized Hierarchical Porous Metal‐Organic Framework Microspheres for Efficient Extraction of Uranium from Seawater

Small, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 12, 2024

Abstract Uranium is a critical resource in the development of nuclear energy, and its extraction from natural seawater has been identified as potential solution to address uranium shortages. In this study, hierarchical meso‐/micro‐ porous metal‐organic framework functionalized with phytic acid (PA) microspheres (denoted H‐UiO‐66‐PA) are rationally synthesized for efficient extraction. This unique design allowed large adsorption capacity fast kinetics, making it promising material Due hierarchically structure, H‐UiO‐66‐NH 2 materials not only provide more sites grafting PA, thus enhance capacity, but also facilitate rapid diffusion uranyl ions which can quickly effectively access interior H‐UiO‐66‐PA adsorbent. Therefore, obtained achieve an impressive absorption efficiency 6.76 mg g −1 actual within 15 days. Meanwhile, possesses good five adsorption/desorption cycles. work proposes feasible strategy constructing functional MOFs removal.

Preparation of fibrous polymer grafted magnetic chitosan beads and modified with hydrazone and imidazole groups: isolation of U(VI) ions from seawater

Journal of Radioanalytical and Nuclear Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: March 29, 2025

Abstract The magnetic chitosan beads were prepared and grafted with glycidylmethacrylate, then diaminomelanonitrile (DAMN) was attached. nitrile groups of DAMN reacted hydrazine hydrate hydrochloride hydrate-ethylene diamine to obtain (HYD) imidazole (IMDZ) groups, respectively. Both adsorbents removed uranyl ions from the aqueous medium seawater. adsorption capacities Fe₃O₄@CHT@p(GMA)-HYD Fe₃O₄@CHT@p(GMA)-IMDZ, 328.4 434.7 mg/g, have high performance for adsorbing U(VI) synthesized used isolate seawater in presence various ions.
