均苯三甲酸合铁同时选择性降低卷烟主流烟气巴豆醛和氢氰酸

Selectively Reducing Butenal and HCN in Mainstream Cigarette Smoke Using Ferric-1,3,5-benzenetricarboxylic Acid

为选择性降低卷烟主流烟气中的巴豆醛和氢氰酸(HCN)的释放量,采用水热合成法制备了金属有机骨架(MOFs)多孔材料均苯三甲酸合铁(Ⅲ)(Fe-BTC),运用X射线粉末衍射(XPRD)、比表面积孔径分析(BET)、扫描电镜(SEM)、热重分析(TG)等技术对合成材料的晶体结构、孔结构参数及热稳定性进行了表征,并将材料添加于卷烟滤嘴中进行了烟气减害测试。结果表明:1)Fe-BTC是一种典型的MOFs多孔材料,在419.7℃以下具有良好的热稳定性。2)与对照卷烟相比,Fe-BTC材料的试验卷烟主流烟气中巴豆醛的选择性降低率可达15.68%、HCN的选择性降低率可达14.44%,而烟气常规成分释放量与对照卷烟基本一致。

In order to Selectively reduce the release of Crotonaldehyde and HCN,the metal-organic frameworks of ferric-1,3,5-benzenetricarboxylic acid（Fe-BTC） was produced by hydrothermal reaction.By means of X-Ray powder diffraction（XPRD）,Brunauer Emmett Teller（BET）,Scanning Electron Microscope（SEM）,Thermogravimetry（TG）,the crystal structure,pore structure and stability were characterized.The result shows that：1） The Fe-BTC was typical MOFs which had good heat stability under 419.7 ℃.2） When Fe-BTC material was added into cigarette filter,up to 15.68% of Butenal and 14.44% of HCN in mainstream cigarette smoke was selectively reduced.While the physical parameters of cigarette and the deliveries of routine smoke components were basically the same as those of reference cigarette.
