▎ 摘　　要

NOVELTY - Device comprises a reaction tank (1) and a filter box (13) which is disposed on the right side of the reaction tank. The reaction tank and the filter box are connected by liquid passing hole (16). A stirring rod (14) is arranged in the reaction tank. An ultrasonic generator (15) is disposed on the left side of the inner bottom of the reaction tank. A filter membrane is disposed inside the filter tank, and the filter membrane is to be filtered inside. A spray head is disposed on an upper portion of the left side surface of the filter membrane. The spray head is mounted on an output end of the electromagnetic valve. An input end of the solenoid valve is connected to an output end of the water pump through a pipe. The water pump is installed at the top of the filter box. An input pipe of the water pump is connected to one end of the pipette, and the other end of the pipette is disposed on the left side of the liquid passage. USE - The device is useful for purifying graphene oxide solution (claimed). ADVANTAGE - The device: is easy to use and increases the speed of reaction solution. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the purifying device. Reaction tank (1) Filter box (13) Stirring rod (14) Ultrasonic generator (15) Liquid passing hole (16)
