摘要
[目的]降低混合型造纸法再造烟叶中TSNAs的释放量。[方法]研究分析不同吸附材料对烟草萃取液及再造烟叶卷烟烟气中TSNAs的吸附效果。[结果]在烟草萃取液中,活性炭对TSNAs的吸附作用优于分子筛,活性炭S35对TSNAs的去除率为84.84%,MCM-41对TSNAs的去除率为48.92%,ZSM-5对TNSAs的去除率最差,仅为6.67%,但其对TSNAs中的NNK具有选择性吸附作用,去除率高达91.60%。通过进一步对再造烟叶卷烟烟气进行试验验证上述结果,活性炭S35对卷烟烟气中TSNAs的去除率为70.20%,MCM-41对TSNAs的去除率为46.74%,ZSM-5对TSNAs的去除率仅为5.57%,ZSM-5对烟气TSNAs中的NNK没有明显的选择吸附作用,去除率为15.64%。[结论]在烟草萃取液中添加吸附材料的方式来降低混合型再造烟叶中TSNAs含量,是一种简易、高效的去除卷烟中TSNAs的方法。
[ Objective] The aim was to reduce TSNAs emissions in mixed paper-making process reconstituted tobaeco.[ Method ] Different adsorbent materials were applied to tobacco extract solution and reconstituted tobacco for removing TSNAs. [ Result] The results showed that the adsorption performance of modified activated carbon was more excellent than molecular sieves in tobacco extract solution. Especially modi- fied aetivated carbon $35 showed the best adsorption performance. The removal rate of TSNAs in tobacco extract solution was 84.84%. The adsorption performance of MCM-41 was greater than ZSM-5, and the removal rate were 48.92% and 6.67% in tobacco extract solution. Meanwhile, ZSM-5 had excellent selective absorption on NNK in tobacco extract solution, and the removal rate was up to 91.60%. The a- mount of TSNAs in tobacco smoke was detected in the same time. Modified activated carbon $35 had the best adsorption performance, the remo- ving rate of TSNAs in tobacco smoke was 70. 20%. MCM-41 showed more .efficient adsorption performance than ZSM-5. The removing rate were 46. 74% and 5.57%, respectively. However, the removal rate of NNK in tobacco smoke was only 15.64% by ZSM-5. [ Conclusion] It＇s a simple, efficient method to reduce the TSNAs in paper-making process reconstituted tobacco by adding adsorbents in tobacco extract solution.
