摘要
为了拦截卷烟主流烟气中的粒相物并去除烟草特有的亚硝胺TSNA,将具有三维网状结构的介孔材料SBA-15-fib尝试用于去除卷烟烟气中的粒相物和亚硝胺。实验表明,三维网状结构使得SBA-15材料能够有效地拦截卷烟烟气中的粒相物,减少焦油含量,同时将烟草特有亚硝胺TSNA在主流烟气中减少40%以上,其中NNN和NNK被去除得尤为明显。
In order to remove tobacco specific nitrosamines（TSNA）,this study tried SBA-15 with specific 3D net-linked morphology as adsorbent to reduce particles and nitrosamines level of tobacco smoke.The results showed that this 3D net-linked SBA-15 could efficiently reduce the content of total particles and tar,and eliminated 40% of TSNA from mainstream smoke when it was used as filter additive of cigarette,and the content of NNN and NNK decreased dramatically as well.
