▎ 摘　　要

NOVELTY - Preparing defect-rich water-stabilized graphene oxide film comprises dispersing graphene oxide powder with water, diluting to obtain a graphene oxide dispersion, adding a mixed solution of hydrogen peroxide and iron (II), loading on the mixed cellulose ester microfiltration membrane by suction filtration, and cleaning to obtain the defect-rich water-stabilized graphene oxide membrane. USE - The method for preparing the defect-rich water-stabilized graphene oxide film useful in water treatment, preferably the water treatment is antibiotics in the water, the filtration separation of dyes and natural organic matter, and the separation of salt ions and dye molecules in salt-containing dyes (claimed). ADVANTAGE - The method has good removing effect for medium molecular weight and macromolecule pollutant in water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for defect-rich water-stabilized graphene oxide film, obtained by the method as mentioned above.
