NOVELTY - Graphene sulfide sponge composite material includes a porous skeleton material and a sulfurized graphene material supported on the surface of the porous skeleton material and inside the porous structure. The porous framework material is a sponge, and the graphene sulfide material has a crosslinked structure formed between sheets of sulfur-containing graphene oxide. USE - Graphene sulfide sponge composite material used in the treatment of industrial wastewater (claimed). ADVANTAGE - The graphene sulfide sponge composite material as a strong adsorption capacity for a variety of metal ions, can realize the adsorption purification of a waste water system with a variety of heavy metals, has high adsorption efficiency, is easy to elute, and can maintain stable adsorption efficiency in an acidic or alkaline solution environment with a pH not greater than 5, and the adsorption performance is not significantly reduced during recycling use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a graphene sulfide sponge composite material, which involves: (A) performing a vulcanization reaction of graphene oxide and a vulcanizing agent in a solvent to obtain sulfur-containing graphene oxide; (B) dispersing sulfur-containing graphene oxide in water to obtain a sulfur-containing graphene oxide dispersion; (C) placing the sponge in a sulfur-containing graphene oxide dispersion liquid for dipping treatment; and (D) taking out the reduction reaction to form a crosslinked structure between the sheets containing sulfur graphene oxide.
