▎ 摘　　要

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 element for water purification apparatus (claimed) for removing bacteria, small molecule organic material, heavy metal, residual chlorine and other radioactive materials in water. ADVANTAGE - The graphene-modified activated carbon composite filter element has high efficiency and deodorization effect, fully absorbs different colors in the water, provides high quality and delicious water, effectively inhibits the growth of bacteria adsorbed on the surface of the filter element and effectively avoids secondary pollution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-modified activated carbon composite filter element, which involves (A) immersing modified activated carbon in graphene solution, filtering solid material, (B) washing and drying the solid material.
