Abstract: PURPOSE: A centrifuge-based continuous synthesizing and refining apparatus of graphene oxide for mass-production and a method for synthesizing and refining the graphene oxide are provided to facilitate a synthesizing and refining process with respect to graphene oxide by implementing a centrifugal process several times. CONSTITUTION: A centrifuge-based continuous synthesizing and refining apparatus of graphene oxide for mass-production includes an injecting part(10) and a discharging part(20). A solution containing graphene oxide, diluted strong acid, or a solvent is injected into the injecting part as a rotor. A solution containing impurities is discharged to the outside of the apparatus through the discharging part. The impurities are separated from the solution containing the graphene oxide based on the rotation of the rotor. The discharging part is operated by an external signal. The discharging part includes a valve.
