▎ 摘　　要

NOVELTY - Preparing reverse osmosis membrane by introducing carboxylated graphene oxide involves immersing sbstrate in the aqueous phase solution to contact, and then drying membrane surface with nitrogen to remove aqueous phase. The treated substrate immersed in the organic phase solution to react, placed in oven for heat treatment to obtain reverse osmosis membrane. USE - Method for preparing reverse osmosis membrane by introducing carboxylated graphene oxide. ADVANTAGE - The method enables to prepare reverse osmosis membrane by introducing carboxylated graphene oxide that improves flux while maintaining a high level of rejection rate, and maintains the retention rate.
