▎ 摘　　要

NOVELTY - A pure graphite rod placed in electrolyte is subjected to electrolysis at 30 plus minus 5 degrees C for 4-6 hours at voltage of 15 plus minus 5 V, and graphite rod is removed from the electrolyte to obtain graphene oxide. The electrolyte comprises 0.4-0.8 mol/l sulfate ion, and 0.6-1.2 mol/l chloride ion or hypochlorite ion. USE - Preparation of graphene oxide (claimed). ADVANTAGE - The method provides graphene oxide by simple, economical and environmentally-friendly process.
