▎ 摘  要

NOVELTY - Rapid purification of enriched graphene oxide crude liquid comprises washing crude graphene oxide solution with hydrochloric acid, centrifuging, re-suspending precipitate with water to obtain suspension, adding water-miscible organic solvent, centrifuging to obtain precipitate and supernatant, adding water-immiscible organic solvent into supernatant, collecting aqueous solution and jelly-like substance at junction of layered layer, and drying obtained precipitates, aqueous solution and jelly-like substance to obtain purified graphene oxide. USE - Method for rapidly purifying enriched graphene oxide crude liquid (claimed). ADVANTAGE - The method has short process duration, simple and easy operation, economic benefits, and high product yield and purity.
