▎ 摘　　要

NOVELTY - Graphene oxide composite carbon film comprises graphene oxide embedded and supported in a porous micro-structure of a carbon film. USE - The film is useful for various water purification devices and water processing engineering equipment. ADVANTAGE - The film has good removal efficiency for residual chlorine, stable structure and improves the removal efficiency of chloroform. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing a graphene oxide composite carbon film, comprising (i) mixing a graphene oxide, an auxiliary agent, a coupling agent and water to obtain a water dispersion of graphene oxide, (ii) immersing the carbon film in the water dispersion of the graphene oxide, supporting the graphene oxide on the surface of the porous structure of the carbon film by hollow suction filtration, and (iii) drying the graphene oxide composite carbon film, and supporting the graphene oxide on the surface of the carbon membrane porous structure by a coupling agent by a thermosetting method at 60-120 degrees C for 30 minutes to 24 hours.
