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.
Abstract
[Objective] The aim was to reduce TSNAs emissions in mixed paper-making process reconstituted tobacco.[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 modified activated carbon S35 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 amount of TSNAs in tobacco smoke was detected in the same time.Modified activated carbon S35 had the best adsorption performance,the removing 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.
