摘要
研究了卷烟嘴棒中分别添加纳米TiO2、纳米SiO2以及纳米Al2O3对卷烟主流烟气中主要有害成分含量的影响。结果显示,纳米SiO2可有效降低主流烟气中苯并[α]芘、苯酚和巴豆醛的含量,而纳米TiO2以及纳米Al2O3则无明显效果,这与它们不同的孔结构密切相关。
Nano-TiO2, nano-SiO2 and nano-Al2O3 were introduced into filter tip respectively, the corresponding effects on the content of poisonous components in mainstream cigarette smoke were investigated. The results showed that nano-SiO2 could effectively reduce the content of phenol, crotonaldehyde and benzopyrene, but these effects were not found for the nano-TiO2 and nano- Al2O3. The result was considered to be associated with the different pore structures of nanomaterials.
