▎ 摘　　要

NOVELTY - Adsorbent comprises cup(6) calixarenes modified magnetic oxide graphene, where cup(6) calixarenes modified magnetic oxide graphene is obtained by calix (6) arene with magnetic oxide graphene through ester bond. USE - Adsorbent for uranium in uranium-containing wastewater (claimed). ADVANTAGE - The adsorbent has excellent adsorption capacity, selectivity and adsorption effect of uranium in low concentration. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for adsorbing uranium in uranium-containing wastewater, which involves mixing uranium-containing waste water for uranium adsorption with adsorbent.
