▎ 摘  要

NOVELTY - Purification of graphene oxide/graphene solution comprises pumping graphene oxide/graphene filtered solution in a channel of a filter discharge tube (6), purifying by the action of electric field between cathodes, filtering out impurities, and pumping the solution in a water tank (3) to form a filtration cycle. USE - Method for the purification of graphene oxide/graphene solution (claimed). ADVANTAGE - The method is simple and inexpensive. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a purifying device, comprising an electrolytic cell comprising cathode discharge tube and filter, filter exhaust pipe, and pump (1). DESCRIPTION OF DRAWING(S) - The drawing is a schematic diagram of the purifying device. Pump (1) Valve (2) Water tank (3) Filter discharge tube (6) Power rectifier (7)
