▎ 摘  要

NOVELTY - Purification of graphene oxide comprises passing graphene oxide solution through cation exchange resin and anion exchange resin, where cation exchange resin is hydrogen type cation exchange resin and anion exchange resin is hydroxide type anion exchange resin. USE - Method for purifying graphene oxide (claimed). ADVANTAGE - The graphene oxide contains less 10 ppm each metal impurity content. The method has high efficiency, uses recyclable ion exchange resin, and is energy-saving and environment-protecting.
