▎ 摘 要
NOVELTY - A metal ion and m-phenylenediamine (organic monomer) are mixed, to form a metal-organic monomer complex with high activity. Graphene oxide is then added and in-situ reduction is carried out, to obtain graphene-metal-poly-m-phenylenediamine composite gel. USE - Preparation of graphene-metal-poly-m-phenylenediamine composite gel used for adsorption of dye (all claimed) e.g. methylene blue. ADVANTAGE - The method enables efficient and economical preparation of graphene-metal-poly-m-phenylenediamine composite gel with monomer conversion rate of 99% or more by simple process. The adsorption rate of methylene blue dye using the composite gel is 615 mg/g. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for usage of graphene-metal-poly-m-phenylenediamine composite gel in adsorption method of dye.
