▎ 摘　　要

NOVELTY - Preparing three-dimensional graphene/covalent organic frameworks (COFs) composite material, comprises suspending three-dimensional graphene hydrogel in dimethyl sulfoxide, mixing with dimethyl sulfoxide solution containing benzene-1,3,5-tricarbaldehyde and benzidine, dropping glacial acetic acid, then stirring at room temperature and reacting to obtain final product. USE - The composite material is useful in enrichment and separation of organic phosphorus (claimed). ADVANTAGE - The method: reduces energy consumption; and is environmentally friendly and economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for three-dimensional graphene/COFs composite material prepared by above mentioned method.
