▎ 摘　　要

NOVELTY - A nitrogen-containing porous carbon material comprises graphene-like carbon layer material as porous carbon material, where the carbon layer is uniformly distributed with micropores and mesopores and the carbon layers are crimped and interlaced to form macropores. USE - The nitrogen-containing porous carbon material is useful for enriching and separating hexachlorocyclohexane pesticide in water bodies (claimed). ADVANTAGE - The porous carbon material achieves rapid, efficient and selective enrichment and separation of hexachlorocyclohexane pesticides in water bodies. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a preparation method of the nitrogen-containing porous carbon material comprising carbonizing oleylamine molecules by pyrolysis method and removing template agent to obtain the product; and (2) an application of the nitrogen-containing porous carbon material in enriching and separating hexachlorocyclohexane pesticides in water bodies.
