▎ 摘　　要

NOVELTY - Enzyme-like ligand-loaded complex ultrafiltration membrane comprises modified organic membrane and enzyme-like ligand loaded on the modified organic membrane. The modified organic film is formed of graphene oxide/polyethyleneimine complex material and high molecular polymer. USE - The enzyme-like ligand-loaded complex ultrafiltration membrane is useful for water treatment (claimed) for removing small-molecule micro-pollutants. ADVANTAGE - The enzyme-like ligand-loaded complex ultrafiltration membrane has high catalytic activity, activates hydrogen peroxide to degrade micro-pollutants in a short period of time, improves removal effect of small-molecule micro-pollutants under low operating pressure and high membrane flux and regenerates enzyme-like ligands in a simple manner, hence has improved long-term use performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing the complex ultrafiltration membrane, which involves immersing the modified organic membrane in a solution containing enzyme-like ligands to obtain a complex ultrafiltration membrane loaded with enzyme-like ligands.
