Preparation of fibrous polymer grafted magnetic chitosan beads and modified with hydrazone and imidazole groups: isolation of U(VI) ions from seawater
Year: 2025
Type: article
Abstract: The magnetic chitosan beads were prepared and grafted with glycidylmethacrylate, then diaminomelanonitrile (DAMN) was attached. The nitrile groups of DAMN were reacted with hydrazine hydrate hydrochloride and hydrazine hydrate-ethylene diamine to obtain hydrazine (HYD) and imidazole (IMDZ) groups, respectively. Both adsorbents removed uranyl ions from the aqueous medium and seawater. The adsorption capacities of the Fe₃O₄@CHT@p(GMA)-HYD and Fe₃O₄@CHT@p(GMA)-IMDZ, beads were 328.4 and 434.7 mg/g, respectively. Both adsorbents have high performance for adsorbing U(VI) ions from seawater. The synthesized adsorbents were used to isolate U(VI) ions from seawater in the presence of various ions.
