NOVELTY - A graphene modified activated carbon composite filter element comprises 0.1-10 %mass graphene and 90-99.9 %mass modified activated carbon. USE - Graphene modified activated carbon composite filter core used in water purifying device (claimed). ADVANTAGE - The influence on mineral element content in the purified water is prevented using filter core. The mineral elements in the water can be kept intact. The filtered water is more beneficial to human health. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene modified activated carbon composite filter core, which involves soaking the modified activated carbon (A) in a graphene solution, drying, treating modified activated carbon (B), spraying a bio-adhesive, calcining treated material (C) in an inert atmosphere, cooling, repeating steps (A-C) (D) to obtain graphene-modified activated carbon composite filter core.
