Abstract:
The magnetic nanocomposite Fe3O4@ZIF-8 was for the first time used as an excellent adsorbent for the fast adsorption and separation of UO22+ ions from aqueous solutions. This material exhibited an unprecedented adsorption capacity of 523.5 mg U per g and a remarkable selectivity towards UO22+/Ln3+ at pH = 3.
