▎ 摘  要

NOVELTY - Preparing graphene oxide separation membrane with adsorption function comprises (a) preparing graphene oxide by Hummers method and centrifuging the reaction solution, (b) adjusting the pH value of the reaction solution to promote formation of precipitate, (c) filtering and separating the precipitate obtained in the step (b), washing and drying to obtain nanohydrous manganese oxide and graphene oxide mixed precipitate, (d) ultrasonically dispersing the mixed precipitate obtained in the step (c) into the water to obtain a film slurry and (e) using the film slurry obtained in the step (d) by film-forming method and heat treatment process on the porous carrier. USE - The method is useful for preparing graphene oxide separation membrane with adsorption function. ADVANTAGE - The membrane: has high separation performance and high adsorption performance (claimed); is environmentally-friendly and economical; has simple production process; has excellent product performance; and has a wide market prospect.
