▎ 摘　　要

NOVELTY - Graphene oxide type adsorption material is formed by performing the polymerization of an aqueous solution of raw material, monomer, crosslinking agent and initiator, where the raw material includes polyvinyl alcohol, humate and graphene oxide. The monomer is acrylic acid. USE - Graphene oxide type adsorption material for removing organic dyes and metal ion pollutants (claimed). ADVANTAGE - The graphene oxide type adsorption material is green and environmentally friendly, has a porous structure, a large specific surface area, simple synthesis process and strong operability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene oxide type adsorption material, which involves: (A) stirring and mixing the polyvinyl alcohol solution and the humate solution, and dispersing uniformly the graphene oxide aqueous under heating conditions to obtain system A; (B) adding the crosslinking agent solution to the acrylic acid solution to obtain system B; (C) dropping the system B and the initiator solution into the system A, and performing the first stirring after, raising the temperature and performing the second stirring to obtain the first precursor; and (D) performing multiple freezing-thawing operations on the first precursor and freeze-drying to obtain a graphite oxide type adsorption material.
