▎ 摘　　要

NOVELTY - Preparing inorganic composite separation membrane containing graphene oxide, comprises (i) dispersing nano-graphene oxide and nano-metal oxide particles in an organic amine aqueous solution to obtain a coating solution; (ii) immersing the supporting membrane material into the coating solution for immersion adsorption and drying to obtain a membrane material body adsorbing nano-graphene oxide and nano-titanium oxide particles; (iii) immersing the obtained film material blank in a polyvinyl alcohol aqueous solution for immersion adsorption, and drying to obtain a film material-coated blank; and (iv) coating the obtained film material on the blank body and subjecting to calcination treatment. USE - The membrane is useful in water treatment, biomedical, chemical, food, and environmental protection fields. ADVANTAGE - The method avoids cracks during the calcination process, increases the flux of the entire composite membrane; and produces product having high flux, high rejection, anti-pollution and good mechanical performance.
