PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing graphene oxide capable of mass-producing graphene oxide by shortening the reaction time.SOLUTION: There are provided a method and an apparatus for producing graphene oxide by significantly shortening the reaction time using an ultrasonic wave, and more specifically, there is provided a method for producing graphene oxide in a short time by applying ultrasonic vibration after completion of the primary reaction by adding graphite and an acid to the reactor body. The method for producing graphene oxide according to the present invention significantly shortens the reaction time using an apparatus equipped with an ultrasonic vibration bar and thus has an advantage capable of increasing the production quantity of graphene oxide and enabling mass production. Since the reaction product can be easily purified using a filter, the methoD has characteristics as compared to the prior art.SELECTED DRAWING: Figure 1 |
