▎ 摘　　要

NOVELTY - Anti-pollution ultrafiltration membrane comprises an ultrafiltration base membrane and a modified layer. The ultrafiltration base membrane is polyacrylonitrile and/or polyvinylidene fluoride. The modified layer is amino acid functionalized graphene quantum dots with visible light photocatalytic function. USE - The anti-pollution ultrafiltration membrane is useful in process of filtering solution containing organic matter (claimed). ADVANTAGE - The method is simple to operate, feasible, and easy for industrial amplification. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing anti-pollution ultrafiltration membrane comprising (1) preparing ultrafiltration basement membrane casting solution, (2) preparing base film containing a non-woven fabric substrate, (3) performing alkali treatment on the base film containing the non-woven fabric substrate to introduce double bonds, and (4) chemically modifying film surface of the base film, introducing amino acid functionalized graphene quantum dots with visible light photocatalytic function.
