Cyclodextrin modified graphene filter membrane and preparation method thereof

The invention discloses a cyclodextrin modified graphene filter membrane and a preparation method thereof, belonging to the field of membrane purification. The preparation method of the graphene filter membrane which is prepared by cyclodextrin modified graphene and used for treating water pollution is simple, convenient in operation and mild in reaction condition; the surface of graphene is modified through cyclodextrin so as to form the filter membrane; and by utilizing the subjective and objective bonding function of cyclodextrin and the high adsorption capacity of graphene, the pollutant molecules in water can be largely adsorbed and effectively removed.
