▎ 摘　　要

NOVELTY - Preparation method for improving chlorine resistance of reverse osmosis membrane comprises using graphene oxide perform material modification of the polyamide membrane, reducing pore size, porosity, hydrophilicity, and surface roughness of the polyamide membrane modified by graphene oxide and chlorine contact activity site, and enhancing the anti-chlorine and antipollution performance of the reverse osmosis composite film. USE - The method is useful for improving chlorine resistance of reverse osmosis membrane. ADVANTAGE - The method reduces pore size, porosity, hydrophilicity, and surface roughness of the polyamide membrane modified by graphene oxide and chlorine contact activity site, and enhances the anti-chlorine and antipollution performance of the reverse osmosis composite film.
