▎ 摘　　要

NOVELTY - An amino acid-metal complex bonded graphene oxide composite ultrafiltration membrane is prepared by chemically bonding amino acids and metal ions on surface of graphene oxide, and dispersing the formed graphene oxide-amino acid-metal ion complex in a polymer solution, and prepared by a non-solvent phase inversion method. USE - Amino acid-metal complex bonded graphene oxide composite ultrafiltration membrane. ADVANTAGE - The amino acid-metal complex bonded graphene oxide composite ultrafiltration membrane has high separation efficiency and flux recovery rate, and is easy to clean. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the amino acid-metal complex bonded graphene oxide composite ultrafiltration membrane.
