▎ 摘　　要

NOVELTY - A graphene oxide-layered hydroxide-supported iron oxyhydroxide composite material is prepared by adding graphene oxide-layered hydroxide composite in 250-1000 mg/L aqueous solution of divalent iron salt under stirring condition in air or oxygen atmosphere, aging and adjusting pH using alkali, filtering, and washing to obtain product. USE - Preparation of graphene oxide-layered hydroxide-supported iron oxyhydroxide composite material for adsorbing heavy metal (claimed). ADVANTAGE - The graphene oxide-layered hydroxide-supported iron oxyhydroxide composite material has improved adsorption performance, especially heavy metal adsorption capacity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for application of composite material of graphene oxide-layered hydroxide supported iron oxyhydroxide for adsorbing heavy metal.
