介微孔材料降低卷烟烟气中氢氰酸的研究进展

Progress in Elimination of Hydrocyanic Acid in Cigarette Smoke by Porous Materials

氢氰酸是卷烟烟气中含量较少且具有挥发性毒性的物质,吸烟时会随着口腔进入人体或者挥发到周围的空气中,不但会抑制人体细胞呼吸酶,造成细胞内窒息,对人体健康造成很大的危害,同时对环境安全也会造成一定的影响。介微孔材料具有较大的比表面积、孔容、孔径和材料表面可修饰性,更重要的是多孔材料大多无毒无害、易制备且能选择性的降低卷烟烟气中的有害物质,因此可以作为吸附剂或者载体应用于卷烟滤嘴中,通过物理吸附和化学吸附选择性的降低卷烟烟气中的氢氰酸。综述了几种以不同方式制备的介微孔材料降低卷烟烟气中氢氰酸的效果,并展望了介微孔材料对于降低卷烟烟气中氢氰酸释放量的研究前景。

Hydrogen cyanide in cigarette smoke is a kind of volatile toxic substance with low content,and it can enter human body or evaporate into the surrounding air while smoking,which would not only inhibit the body cell respiration enzymes and intracellular asphyxia to cause extreme harm to human body health,but influence safety environment.Porous material can be used as adsorbent and catalyst in cigarette filter by physical adsorption and chemical adsorption to reduce hydrogen cyanide in cigarette smoke because of its large specific surface area,entrance,aperture,and material surface modification,what′s more,porous materials are non-toxic and harmless,and it can selectively reduce harmful substances in cigarette smoke.In this review,porous materials are prepared in different ways to reduce the effects of hydrogen cyanide in cigarette smoke.Finally,porous materials is prospected to reduce the content of hydrogen cyanide in cigarette smoke.
