▎ 摘　　要

NOVELTY - A cyclodextrin modified graphene filter membrane is prepared by utilizing 0.4-0.6 mg/ml graphene oxide solution, and 16-24 ml cyclodextrin solution and 240-360 mu l 3.2-4.8mg/ml ammonia water, adding hydrazine hydrate to the mixture, fully mixing to obtain the mixed solution, heating the mixture at 50-70 degrees C in water bath for 3-4 hours, to obtain black uniform dispersion of water solution, followed by mixing the solution with a cellulose ester micro-porous filtering film, drying to obtain finished product. USE - Cyclodextrin modified graphene filter membrane for treating water pollution. ADVANTAGE - The membrane has high adsorption capacity of graphene, the pollutant molecules in water and effectively removed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing cyclodextrin modified graphene filter membrane.
