▎ 摘　　要

NOVELTY - A graphene-sterilizing compound filter element comprises 90-99 mass% activated carbon, 0.5-9.5 mass% graphene material, 0.1-1 mass% surface active agent and 0.1-5 mass% additive, where the additive comprises polyacrylic acid, FOF, KDF55, cationic polyacrylamide, sodium gluconate, maleic anhydride, polyaspartic acid, polyepoxysuccinic acid and trimethylolaminomethane. USE - Graphene-sterilizing compound filter element for use in water purifiers. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a graphene-sterilizing compound filter element, which involves weighing each raw material, preparing a graphene-modified activated carbon, pulverizing the graphene-modified activated carbon and utilizing the powder to obtain the finished product.
