▎ 摘　　要

NOVELTY - A composite film based on cooperative separation and photo-Fenton self-cleaning comprises graphene oxide, polyacrylic acid and metal-organic framework NH2-MIL-88B(iron). USE - Used as composite film based on cooperative separation and photo-Fenton self-cleaning. ADVANTAGE - The composite film efficiently keeps retention rate of dye while improving water flux, has self-cleaning effect, and provides an unique idea for commercial popularization of graphene oxide film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for: a method for preparing the composite film.
