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.
