▎ 摘　　要

NOVELTY - The system (10) configured to produce graphene oxide using graphite oxidized by an acid and a salt, comprises: a centrifugal separation unit configured to perform a deacidification treatment for removing acid from the graphite oxide by centrifuging a dispersion of graphite oxide obtained by oxidizing graphite; and a filtration unit for performing a filtration treatment on the dispersion of the deoxidized graphite oxide, where the filtration unit is configured to allow a liquid containing impurities to pass through the filtration filter (182) and to be discharged as a filtrate, while capturing graphite oxide with a filtration filter. The filtering unit has a layer thickness adjusting unit configured to apply a force to the cake layer for adjusting the deposited thickness of the cake layer containing the graphite oxide trapped in the filtering filter. USE - The system is used for producing graphene oxide. ADVANTAGE - The system produces high-quality graphene oxide while suppressing equipment costs. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene oxide production system. 10Graphene oxide production system 12Oxidation reactor 14Oxidation reaction stopping device 15Refining department 16Centrifuge 18Rotary filtration device 182Filtration filter 184Layer thickness adjustment blade
