▎ 摘　　要

NOVELTY - Graphene-based membrane comprises at least two graphene-oxide layers. Each of the graphene oxide layers comprises many graphene-oxide flakes, where each graphene-oxide flake comprises a planar graphene structure with oxygen moieties extending from it. The graphene-based membrane has a thickness of 2-20 nm. USE - The graphene-based membrane is useful: for removing ions from water (claimed) including radioactive ions; and in desalination process, treating shale gas production water, and nuclear waste water treatment. ADVANTAGE - The graphene-based membrane exhibits high selectivity in removing ions from water.
