▎ 摘　　要

NOVELTY - The method comprises dispersing graphene oxide in deionized water for ultrasonic 2 hours to obtain graphene oxide dispersion liquid, sealing it in glass bottle after being saturated with an inert gas for 30 minutes, exposing it under 60Co gamma ray irradiation source to obtain porous graphene oxide solution, centrifuging graphene oxide solution after irradiation to collect supernatant, filtering the supernatant to polyether sulfone base film, and drying at room temperature to obtain porous graphene oxide film. USE - Preparation method for assembling film by gamma ray irradiation etching graphene oxide used in water purification and gas purification. ADVANTAGE - The film prepared by the method is used for recycling efficient dye waste water with excellent permeability and separation performance, and simple preparation method, strong controllability, green and environment-friendly, which develops novel way for manufacturing high performance two-dimensional laminated film for purifying waste water and recycling.
