▎ 摘　　要

NOVELTY - A graphene scale-composite filter element comprises 90-99 wt.% activated carbon, 0.1-9.8 wt.% graphene materials, 0.1-1 wt.% surfactants, and 0.1-5 wt.% additives, where the additives comprises polyacrylamide, FOF, cationic polyacrylamide, polyphosphate, chelating resin, maleic anhydride, polyaspartic acid, and polyepoxysuccinic acid. USE - Graphene scale-composite filter element for use in water purifiers under various conditions. ADVANTAGE - The graphene scale-composite filter element has excellent descaling function, and better function of effectively removing scales contained in water, purifying water quality, and protecting people's health. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a graphene scale-composite filter element, which involves weighing each raw material in proportion, preparing graphene-modified activated carbon, pulverizing the graphene-modified activated carbon, and using the powder to obtain the finished product.
