▎ 摘　　要

NOVELTY - Preparation of carboxyl graphene oxide/metal-organic frameworks (MOFs) composite material involves (s1) carboxylating graphene oxide to obtain carboxylated graphene oxide, and (s2) placing activated MOFs material and carboxylated graphene oxide in organic solvent, stirring and reacting at 95-105℃, and freeze-drying. USE - Preparation of carboxyl graphene oxide/metal-organic frameworks composite material used for absorbing heavy metal ions e.g. lead (II), cadmium (II), copper (II), nickel (II), and cobalt (II) in water (all claimed). ADVANTAGE - The material can effectively absorb heavy metal ion in water.
