▎ 摘　　要

NOVELTY - The system has an electrolysis device (2) with an electrolysis vessel (20). The electrolytic vessel is configured to contain electrolyte and provide place for an electrolytic reaction. The electrolytic vessel includes a first liquid inlet and a first liquid outlet. A circulation circuit communicates with the first liquid inlet and the first liquid outlet. A solid-liquid separation device is connected in series to the circulation circuit. The solid-liquid separation device includes a second liquid inlet (31), a second liquid outlet (32), and a filter screen (33). The second liquid inlet and the second liquid outlet are connected to the circulation circuit, and the filter screen is located between the second liquid inlet and the second liquid outlet. USE - Electrolytic system for preparing graphene oxide material by illumination. ADVANTAGE - The special illumination improves the oxidation degree of the product. The mass production of graphene oxide is realized. The method is safe, environment friendly and time-saving for preparing graphene material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for electrolytic method for preparing graphene oxide material by illumination. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of electrolytic system.
