▎ 摘　　要

NOVELTY - The preparation method of flue gas adsorption graphene porous material involves: (1) performing ultrasonic treatment of graphene oxide compound with aqueous solution at 20-25 kHz for 10-40 minutes; (2) freeze-drying treatment liquid obtained in step (1) to obtain graphene oxide porous material; and (3) performing thermal reduction of graphene oxide porous material obtained in step (2). USE - The method is useful for preparing flue gas adsorption graphene porous material, which is useful for adsorption of phenol, resorcinol, citral, formic acid, acetic acid, butyric acid, n-valeric acid, isovaleric acid, palmitic acid, linolenic acid, pyridine or pyrrole (claimed). ADVANTAGE - The method enables simple preparation of flue gas adsorption graphene porous material in an environmentally-friendly manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of graphene porous material for adsorption of phenol, resorcinol, citral, formic acid, acetic acid, butyric acid, n-valeric acid, isovaleric acid, palmitic acid, linolenic acid, pyridine or pyrrole.
