▎ 摘　　要

NOVELTY - Preparing magnetic graphene-based metal-organic frameworks (MOFs) hybrid film comprises supporting iron (II,III) oxide magnetic microspheres on the surface of graphene by a hydrothermal method, and then magnetic using graphene as a carrier. Zinc oxide is loaded on its surface to obtain zinc oxide-modified magnetic graphene. The magnetic graphene-based MOFs hybrid film is synthesized in situ with zinc oxide as the metal source by using the solvent etching effect. USE - Method for preparing magnetic graphene-based metal-organic frameworks hybrid film for adsorption and removal of trace phenolic endocrine disruptors in water environment (claimed). ADVANTAGE - The method prepares the hybrid film in a simple manner with good chemical stability and reusability, has strong magnetic responsiveness, predictability and practicability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using magnetic graphene-based metal-organic frameworks hybrid film, which involves preparing an actual water sample of phenolic endocrine disruptors at pH 7, adding the magnetic graphene-based MOFs hybrid membrane to the water sample for oscillating adsorption, enriching with an external magnet, and considering temperature, adsorption time and substrate adsorption efficiency of the magnetic graphene-based MOFs hybrid film on the basis of concentration influencing factors and recycling rate.
