▎ 摘 要
NOVELTY - Graphene oxide is dispersed to N,N'-dimethylformamide, and aminopropyl silica gel, N,N'-dicyclohexyl carbodiimide and 4-dimethylaminopyridine as catalyst are added, reacted at 45-50 degrees C under normal pressure, filtered and dried to obtain graphene oxide-bonded silica gel. The obtained graphene oxide-bonded silica gel is added to an aqueous solution of hydrazine hydrate, reacted at 90-100 degrees C, filtered and dried to obtain graphene-bonded silica stationary phase. USE - Preparation of graphene-bonded silica stationary phase (claimed). ADVANTAGE - The method efficiently provides graphene-bonded silica stationary phase having high stability, by simple method.
