摘要
为选择性降低卷烟主流烟气中氢氰酸(HCN)的释放量,制备了一种胺基功能化的介孔二氧化硅材料(MCM-41-NH2),运用扫描电镜(SEM)、X-射线衍射(XRD)、比表面积孔径分析(BET)以及13C固体核磁共振谱(13C-NMR)对材料进行了表征,并将材料添加于卷烟滤嘴进行了烟气减害测试。结果表明:①与MCM-41材料相比,MCM-41-NH2的晶型无明显改变,但孔径和比表面积下降了50%。②该材料对卷烟主流烟气中HCN的选择性降低率达到25.7%,而烟支物理参数及烟气常规成分释放量与对照卷烟基本一致。
In order to selectively reduce the delivery of HCN in mainstream cigarette smoke, an amino-functionalized mesoporous silica material （MCM-41-NH2） was prepared and characterized by means of scanning electron microscopy （SEM）, X-ray diffraction （XRD）, specific surface area and pore size analyzer （BET） and ~3C solid-state nuclear magnetic resonance （NMR）, then the prepared material was applied to cigarette filter to reduce the deliveries of harmful components in cigarette smoke. The results showed that： 1） Comparing with MCM-41 material, the crystal form of MCM-41-NH2 did not change significantly, however its pore size and specific surface area were reduced by 50%. 2） When MCM-41-NH2 material was added into cigarette filter, up to 25.7% 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.
