摘要
采用饱和水溶液法制备荆芥挥发油-β-CD包合物,并用紫外可见分光光度法、X-射线衍射对包合物进行表征。研究了β-CD和荆芥挥发油-β-CD包合物吸附溶液中苯酚的性能。此外,还将β-CD以及荆芥挥发油-β-CD包合物作为添加剂添加到卷烟滤嘴中,研究其对卷烟主流烟气中苯酚的影响。结果表明,β-CD和荆芥挥发油-β-CD包合物吸附溶液中苯酚的动力学模型都是准二级动力学模型。当添加剂用量为30mg时,β-CD以及荆芥挥发油-β-CD包合物对卷烟主流烟气中苯酚的降低率分别为74.01%和88.9%。此外,添加剂还可以有效降低卷烟主流烟气中总粒相物的含量。
Schizonepeta oil-β-cyclodextrin inclusion compounds were prepared by saturated aqueous solution method and characterized by UV-visible spectrophotometry and X-ray diffraction. β-cyclodextrin and Schizonepeta oil-β-cyclodextrin inclusion compounds were used as adsorbent to adsorb phenol in aqueous solution. Besides, β-cyclodextrin and Schizonepeta oil-β-cyelodextrin inclusion compounds were added to cigarette filters to study their effects on reducing phenol in mainstream cigarette smoke. The results showed that the adsorption kinetic data were fitted well by the pseudo second-order kinetic model, and when the weight of additive was 30 rag, 74.01% and 88.9% of phenol in mainstream cigarette smoke could be re- duced. Furthermore, the total particle matter in mainstream cigareete smoke could also be reduced effi- ciently.
