▎ 摘  要

NOVELTY - Preparing graphene adsorbent comprises adding mixed solution of water and ethanol into the graphene oxide and acrylic acid, stirring for 1-2 hours, adding N, N-methylenebisacrylamide and potassium persulfate, stirring for 0.5-1 hour, reacting for 5-12 hours under nitrogen protection, cooling, filtering, washing, neutralizing, drying and grinding. USE - The adsorbent is useful for recovering dilute element gallium (claimed). ADVANTAGE - The method is simple and economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for recovering dilute element gallium using graphene adsorbent, comprising adding graphene adsorbents into solution containing gallium ions and carrying out static adsorption for15-24 hours.
