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.
