▎ 摘　　要

NOVELTY - Preparing graphene oxide composite forward osmosis membrane, comprises preparing a mixed solution, where the mixed solution is an aqueous dispersion comprising graphene oxide and acidified carbon nanotubes, and the mass ratio of graphene oxide to acidified carbon nanotubes is 2-18, vacuum-filtering the mixed solution to form a membrane, and drying the membrane to obtain a graphene oxide composite forward osmosis membrane. USE - The method is useful for preparing graphene oxide composite forward osmosis membrane. ADVANTAGE - The method is simple and efficient, and can prepare the positive osmosis water treatment film with good interception performance, high water flux, good sterilizing performance and can be applied in large scale. The film prepared by this method has more excellent antibacterial performance while the water flux is increased. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an oxidation-graphene composite forward osmosis membrane, comprising an graphene and acidification carbon nano-tube.
