▎ 摘　　要

NOVELTY - Preparation of nitrogen doped reduced graphene oxide nanocomposite comprises mixing chitosan, glacial acetic acid and water to obtain chitosan acetic acid aqueous solution, mixing graphene oxide with water to obtain graphene oxide aqueous dispersion, mixing chitosan acetic acid aqueous solution with graphene oxide aqueous dispersion solution to obtain chitosan/graphene oxide powder, freeze drying and performing thermal reduction reaction on chitosan/graphene oxide powder. USE - The preparation of nitrogen doped reduced graphene oxide nanocomposite is used for treatment of phenol containing wastewater (claimed). ADVANTAGE - The method improves removal efficiency of nitrogen doped reduced graphene oxide nano composite material for phenolic pollutants and provides convenient conditions for subsequent treatment.
