▎ 摘　　要

NOVELTY - Molybdenum disulfide oxide-graphene oxide-polyetherimide composite ceramic nanofiltration membrane comprises a porous ceramic membrane support body and an organic functional layer arranged on the porous ceramic membrane support the body. The porous ceramic membrane support body includes an organic function layer. The surface is loaded with a silane coupling agent, where the organic functional layer is formed by using the mixed aqueous solution of molybdenum disulfide oxide and graphene oxide and the polyethyleneimine aqueous solution as raw materials and alternately compounded on the porous ceramic membrane support through layer-by-layer self-assembly. The amino group on the coupling agent reacts with the hydroxyl group on graphene oxide and molybdenum disulfide oxide. USE - Oxidation molybdenum disulfide-graphene oxide-peI composite ceramic nano-filtration membrane for water treatment. ADVANTAGE - The molybdenum disulfide/graphene oxide/PEI composite ceramic nano-filtration membrane has higher desalting rate to magnesium sulfate solution, high pure water flux, and good acid and alkali resistance performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing molybdenum disulfide oxide-graphene oxide-polyetherimide composite ceramic nanofiltration membrane, which involves: preparing molybdenum disulfide oxide by improved Hummers method and graphene oxide to obtain a mixed aqueous solution, and then using the mixed aqueous solution and polyethyleneimine aqueous solution as raw materials through layer-by-layer self-assembly and strong alkali activation and grafting described silane coupling to form organic functional layer on the porous ceramic membrane support of the agent.
