▎ 摘  要

NOVELTY - Construction of zeolitic imidazolate framework-8-doped graphene oxide hybridized or zeolitic imidazolate framework-8-doped flake-graphite oxide membrane comprises pretreating porous base film to remove surface organic matter, inorganic substances and microorganisms; dispersing graphite oxide powder in deionized water, ultrasonic centrifuging, vacuum filtering, and assembling onto surface of the porous base film; freeze-drying; arranging zeolitic imidazolate framework-8 precursor solution in a certain molar ratio of zinc nitrate hexahydrate and 2-methylimidazole; and filling in the porous composite graphite oxide composite film and nucleate crystallizing in lye. USE - Method for constructing zeolitic imidazolate framework-8-doped graphene oxide hybridized or zeolitic imidazolate framework-8-doped flake-graphite oxide membrane used for filtration separation of dyes and high-priced salts in water, small molecules in organic phase, and gas separation (claimed). ADVANTAGE - The membrane has good separating property and stability.
