▎ 摘  要

NOVELTY - Preparing adsorption material involves mixing the chitosan, glacial acetic acid, glutaraldehyde and water for crosslinking to obtain cross-linked chitosan, mixing the obtained cross-linked chitosan and cinnamic acid for grafting reaction to obtain modified chitosan, mixing the modified chitosan, graphene oxide suspension and glutaraldehyde, adjusting pH to be neutral to obtain product. USE - Method for preparing adsorption material used for water pollution treatment. ADVANTAGE - The material has good mechanical strength and stability and overcomes the defects that the graphene is easy to accumulate and has bad dispersibility.
