▎ 摘　　要

NOVELTY - Graphene oxide composite membrane comprises a dopamine-modified hollow fiber support and a crosslinked graphene separation layer embedded with manganese dioxide nanobelts. The crosslinked graphene separation layer embedded with manganese dioxide nanobelts is composed of layer-by-layer stacked crosslinked graphene sheets and manganese dioxide nanobelts. USE - The graphene oxide composite membrane is useful for separating antibiotic waste water. ADVANTAGE - The graphene oxide composite membrane has high water flux and high antibiotic rejection rate. The method is simple and convenient to operate, economical and general in use, and environmentally friendly, and has good application prospects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing graphene oxide composite membrane used for separating antibiotic waste water.
