NOVELTY - The device has an air duct whose end penetrates through one side of the outer wall of a reaction chamber (5) and extends to the inside of the reaction chamber. A ventilation hood is installed at one end of the air duct. A water pump is fixedly installed on the top surface of the reaction chamber. The outlet end of the water pump is fixedly sleeved with a water pipe. One end of the water pipe penetrates through the top surface of the reaction chamber and extends to the inside of the reaction chamber and is fixedly installed with the rotating multi-tube nozzle. A second one-way valve is installed on the other side of the outer wall at the bottom of the reaction chamber. USE - Purification device for graphene oxide. ADVANTAGE - The graphite powder is screened and clogged filter membranes are automatically replaced. The inner wall surface of the reaction chamber is quickly and effectively cleaned and dried. The purity of graphene oxide obtained after purification is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a purification method of graphene oxide purification device. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the purification device for graphene oxide.
