▎ 摘　　要

NOVELTY - Graphene oxide-based composite material doped with porous metal organic framework useful for dye separation or solvent purification comprises porous metal organic framework and graphene oxide. USE - The porous metal organic framework-doped graphene oxide-based composite material is useful for dye separation or solvent purification (claimed). ADVANTAGE - The material shortens the filtration time of the composite material, and has higher water flux and stronger mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for rapid preparation method of porous metal organic framework-doped graphene oxide-based composite membrane or composite hydrogel, comprising diluting the porous metal organic framework and graphene oxide to a concentration of 0.1-20 mg/ml with diluent, mixing the two according to the ratio after the ultrasonic dispersion is uniform, stirring the mixture uniformly, and filtering with an auxiliary filtration method.
