NOVELTY - Invention relates to chemical industry and nanotechnology. First, graphite is treated with hydrogen peroxide solution in sulphuric acid, wherein amount of hydrogen peroxide is from 0.15 to 0.30 pts.wt. by 1 pts.wt. graphite in conversion to 100% hydrogen peroxide with total concentration of free water in reaction mixture, not exceeding 0.5% taking into account water formed in reaction H2O2+ H2SO4= H2SO5+ H2O. Further, water is added to the reaction mixture in such an amount that free water concentration is close to 2%. Then potassium permanganate is added while maintaining free water concentration. Water is added to the obtained reaction mixture in an amount which provides concentration of free water close to 5%, and hydrogen peroxide is added again. Obtained carbon-containing oxidation product is washed with an acid solution, then with water. USE - Chemistry. ADVANTAGE - Method of producing graphene oxide is environmentally friendly and is suitable for industrial production. 1 cl, 1 dwg, 1 tbl, 1 ex
