NOVELTY - Preparation of reduced graphene oxide involves mixing solid graphene oxide and water, obtaining suspension, stirring obtained suspension, ultrasonically treating, obtaining uniform graphene oxide dispersion solution, mixing with anhydrous glucose, stirring for 30-60 minutes, adding ammonia, stirring continuously for 5-10 minutes, increasing the temperature to 95 degrees C for 40-60 minutes, terminating reaction, cooling to room temperature, filtering, washing obtained filter cake using water until neutral, and drying. USE - Preparation of reduced graphene oxide used for adsorbing cationic dye, anionic dye and nonionic dye (all claimed). ADVANTAGE - The method efficiently provides reduced graphene oxide having excellent adsorption property with respect to low-concentration dye with concentration of less than 100 mg/L, by simple method. DETAILED DESCRIPTION - Preparation of reduced graphene oxide involves mixing solid graphene oxide and water in the solid-liquid ratio of 1:800-1000, obtaining suspension, stirring obtained suspension, ultrasonically treating, obtaining uniform graphene oxide dispersion solution, mixing with anhydrous glucose in the solid-liquid ratio of 12-16:1, stirring for 30-60 minutes, adding ammonia in the solid-liquid ratio of 6-8:1, stirring continuously for 5-10 minutes, increasing the temperature to 95 degrees C for 40-60 minutes, terminating reaction, cooling to room temperature, filtering, washing obtained filter cake using water until neutral, and drying.
