【Abstract】 Zeolites ZSM-5 and Y can adsorb the polycyclic aromatic hydrocarbons and nitrosamines in gaseous phase, and reduce the pollution of smoking. In this article, the influence of zeolite type and their surface acidic-basic properties on the selective adsorption of these harmful components is examined. As revealed in this paper, coating copper compounds on the surface of Y significantly enhances the adsorption efficiency of zeolite. This novel material with nano-pore structure can effectively reduce 30%～60% of harmful content like polycyclic aromatic hydrocarbons and nitrosamines in cigarette smoke.更多还原
