NOVELTY - Preparing graphene oxide and/or grafenomediante through control of oxidation reaction on graffiti material involves dispersing graffiti material using a solvent or mixtures or pre-oxidation of the graffiti material, irradiating on the graffiti material dispersion with microwaves at different times, temperature and power, and performing oxidation of the graffiti material from the control of the reaction rate of the oxidizing substance. The degraphite oxide exfoliation is performed through microwave radiation and/or ultrasound or other mechanical process. USE - Method for preparing graphene oxide and/or grafenomediante through control of oxidation reaction on graffiti material. ADVANTAGE - The method enables to prepare graphene oxide through control of oxidation reaction on graffiti material that controls the incorporation of oxygen during the reaction of oxidation of graphitic material.
