▎ 摘　　要

NOVELTY - The method comprises using the selective permeability of porous hydrogen passivated graphene film to methanol, adsorbing methanol on the electrode plate through the graphene film under the action of electric field to remove methanol in the wastewater. USE - Method for removing methanol in wastewater using a passivated graphene film capacitor deionization device, which is used in the field of environmental protection. ADVANTAGE - The method can realize low-cost removal of methanol in waste water. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of a method for removing methanol in wastewater using a passivated graphene film capacitor deionization device (Drawing includes non-English language text).
