▎ 摘　　要

NOVELTY - A graphene adsorption material comprises graphene-loaded fiber carrier and doping element, where doping element is aluminum, silicon, and/or iron. USE - Graphene adsorption material used for flue gas filter apparatus (claimed). ADVANTAGE - The adsorption material removes flue gas such as benzopyrene polycyclic aromatic hydrocarbons and harmful substances carcinogens, retains nicotine, does not affect the smoke flavor, reduces the dangers of smoking, has mellow smoke flavor, and prevents moisture and damp moldy phenomenon. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of graphene adsorption material comprising contacting fibers with graphene material and loading; and (2) flue gas filter apparatus comprising cigarette filter, air filter, or exhaust unit.
