▎ 摘  要

NOVELTY - Preparation of hydrophobic modified graphene oxide reverse osmosis membrane involves using polysulfone ultrafiltration membrane as base membrane, m-phenylenediamine as aqueous phase monomer, trimesoyl chloride as oil phase monomer, and octadecylamine modified graphene oxide as oil phase additive, n-hexane as oil phase solvent, and carrying out interfacial polymerization. USE - Preparation of hydrophobic modified graphene oxide reverse osmosis membrane. ADVANTAGE - The method produces reverse osmosis membrane having high flux and high salt rejection rate.
