▎ 摘　　要

NOVELTY - Carbon-based nano filtration membrane comprises a membrane surface-active layer attached to an organic ultra-filtration base membrane. The membrane surface-active layer is a modified graphene oxide layer. The modified graphene oxide sheet is loaded with multiwalled carbon nanotubes (7) and an α- ferric oxide nanoparticle (13) loaded on a graphene oxide layer (14). The material of the organic ultra filtration base membrane is polyethersulfone. USE - The carbon-based nano filtration membrane is useful for water treatment (claimed). ADVANTAGE - The carbon-based nano filtration membrane has high mechanical strength and does not easy to break, and maintains higher permeation flux and removal rate in the process of high-salt solution treatment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing carbon-based nano filtration membrane. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the carbon-based nanofiltration membrane for water treatment. 7Multi-wall carbon nano tube 13Alpha- ferric oxide nanoparticle 14Graphene oxide layer
