▎ 摘　　要

NOVELTY - Manufacture of three-dimensional graphene adsorption material involves adding graphite oxide to a solvent, adding a surfactant, ultrasonically treating, cooling to room temperature to obtain a graphite oxide aqueous solution, immersing a polyurethane sponge in the graphite oxide solution, stirring, separating the solid product, vacuum drying, and heating in an inert atmosphere. USE - Manufacture of three-dimensional graphene adsorption material for treating sewage (claimed). ADVANTAGE - The three-dimensional graphene adsorption material having excellent stability, acid resistance, alkali resistance and absorption effect with respect to organic dyes, preferably methyl orange is prepared industrially by simple method.
