▎ 摘　　要

NOVELTY - A surface-chemically grafted graphene oxide modified polyamide reverse osmosis membrane is prepared by utilizing polyamino compound as a linker, 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and N-hydroxysuccinimide as catalysts, catalyzing the amidation reaction of the aromatic polyamide composite reverse osmosis membrane and graphene oxide to realize the carboxyl group connection of the carboxyl group on the surface of the polyamide composite reverse osmosis membrane and the carboxyl group of the graphene oxide layer to prepare the modified polyamide reverse osmosis membrane having one or more layers of graphene oxide grafted on the surface. USE - Surface-chemically grafted graphene oxide modified polyamide reverse osmosis membrane. ADVANTAGE - The surface-chemically grafted graphene oxide modified polyamide reverse osmosis membrane can be prepared with better inoxidability and better chlorine resistance, and effectively improving a chlorine resistant polyamide reverse osmosis membrane and prolonging the service life.
