▎ 摘　　要

NOVELTY - Washing oxide graphene involves separating the unreacted sulfuric acid from the oxide graphene slurry and washing the above-mentioned separated oxide graphene by using the aqueous solution. USE - Method for washing oxide graphene in washing device (claimed). ADVANTAGE - The method enables to wash oxide graphene in efficient manner which washes in a short time and reduces the waste water generation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a oxide graphene manufacturing device, which comprises graphite oxidation unit (310), peeling unit (320) in which the oxidation graphite oxidized in the graphite oxidation unit (312) is exfoliated and consisting of the oxide graphene and the oxide graphene rinse unit (330). DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a oxide graphene manufacturing device.
