摘要
使用ZSM-5和Y沸石吸附气相中的多环芳烃和亚硝胺,能减少吸烟对于环境的污染。报道了沸石类型和酸碱性对于吸附性能的影响。使用表面涂布铜化合物的新技术显著提高Y沸石的吸附效率,这种复合纳米孔材料可以有效地减少卷烟烟气里30%～60%的多环芳烃和亚硝胺等有害物质。
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.
