▎ 摘  要

NOVELTY - Method for preparing super hydrophilic-modified super-oleophobic separation membrane involves dispersing graphene oxide and one-dimensional single-walled aluminosilicate nanotubes in deionized water to form a mixed dispersion, depositing the graphene oxide and the one-dimensional single-walled aluminosilicate nanotubes in the mixed dispersion on the surface of the polymer microfiltration membrane and drying to obtain the product. USE - The method is useful for preparing super hydrophilic-modified super-oleophobic separation membrane used in oil-water separation apparatus (claimed). ADVANTAGE - The method has super-hydrophilicity and super-oleophobicity under water, excellent stability, high oil-water separation efficiency and simple preparation process, effectively separates oil-water aqueous emulsion, is safe, economical, environmentally-friendly and suitable for large-scale industrial production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) an oil-water separation apparatus comprising the separation membrane; and (2) a method for processing oil-water separation involving passing an oil-water mixing system through the separation membrane to achieve oil-water separation, where the oil-water mixing system is an oil-water aqueous emulsion.
