▎ 摘　　要

NOVELTY - Preparing molecularly imprinting graphene composite material, involves uniformly dispersing graphene oxide in the buffering liquid to obtain graphene oxide dispersion liquid, adding hydrochloric acid in dopamine and template molecules, stirring mixed liquid, then carrying out centrifugal washing, and finally eluting to remove template molecules and obtaining molecular imprinted graphene composite material. USE - For preparing molecularly imprinting graphene composite material (claimed). ADVANTAGE - The method has mild reaction condition and high-efficiency; is green and environment-friendly; and has low cost. The obtained molecular imprinted graphene composite material on the template molecules provides high binding capacity, rapid and specific recognition, etc.
