▎ 摘　　要

NOVELTY - Purifying graphene involves dissolving graphene to be purified in organic solvent to obtain mixed solution of graphene. The electromagnet suspension is placed on graphene in mixed solution. The electromagnet is electrified to generate magnetism and maintained for predetermined time and stirred graphene solution to absorbed graphene on magnet surface and take electromagnet of surface-adsorbed graphene. The electromagnet loses magnetism is powered off and is collected from electromagnet surface of graphite and dried to obtain graphene after purified. USE - Method for purifying graphene. ADVANTAGE - The method enables to purify graphene that has high purification efficiency, and in simple manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphite purifying device, which comprises container containing graphene mixed solution and electromagnet which is used to electrifying electromagnet causes electromagnet to magnetic source.
