NOVELTY - Microwave-assisted rapid synthesis of graphite oxide involves mixing graphite, sulfuric acid and potassium permanganate in a flask, stirring, reacting at -5 degrees C to 5 degrees C for 60-90 minutes, adding the reaction solution to Teflon (RTM: polytetrafluoroethylene) reaction tank, placing the reaction tank in a microwave oven, rapidly oxidizing under microwave, taking out the reaction tank, washing the reaction product, and drying in an oven to constant weight. USE - Microwave-assisted rapid synthesis of graphite oxide used for preparing graphene and as carrier in combination with inorganic or organic compounds for photocatalytic or Fenton's reaction system, and for effective degradation of dye wastewater (all claimed). ADVANTAGE - The method enables simple, economical and rapid synthesis of environmentally-friendly graphite oxide using easily available raw materials.
