▎ 摘　　要

NOVELTY - Use of graphene adsorption material in reducing harmful components in cigarette smoke. The graphene adsorption material is graphene oxide activated by potassium hydroxide, prepared by reducing with hydrazine hydrate as a reducing agent, and adding graphene adsorbent into cigarette filter to achieve the purpose of reducing harmful components in cigarettes. USE - The graphene absorbing material is useful in reducing harmful components in cigarette smoke. ADVANTAGE - The graphene absorbing material has good adsorption effect, simple preparation method, mild reaction condition, large specific surface area, stable regular hexagonal lattice structure, and easy to form acid-base conjugated interaction with phenolic compound. The cigarette filter additive can effectively reduce the harmful components in the flue gas. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of graphene adsorption material.
