▎ 摘  要

NOVELTY - Titanium dioxide graphene oxide modified organic ultrafiltration membrane, comprises organic ultrafiltration membrane supporting body and functional layer. The functional layer is formed on the surface of the organic ultrafiltration membrane supporting body by filtration and drying of an aqueous solution of titanium dioxide and graphene oxide with pH=3-5. The titanium dioxide graphene oxide aqueous solution is prepared by the sol-gel method with the graphene oxide aqueous solution and the alcohol solution of the titanium organic salt as raw materials, and the concentration is 2-5 mg/l. The nano-titania is uniformly supported on the graphene oxide sheet. The material of the organic ultrafiltration membrane supporting body is polyethersulfone or polycarbonate. USE - Titanium dioxide graphene oxide modified organic ultrafiltration membrane used in membrane material preparation field for processing organic pollutant. ADVANTAGE - The titanium dioxide graphene oxide modified organic ultra-filtration membrane increases the hydrophilic performance of the film layer and improves the photo-catalytic effect, specifically under the UV light irradiation and 0.1 MPa test condition, the 1 g/l of bovine serum albumin has high flux and interception rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing titanium dioxide graphene oxide modified organic ultrafiltration membrane.
