摘要 文章分别采用气液微萃取与气固微萃取技术,以对羟基苯甲酸为捕集剂捕集香烟烟气中的羟基自由基。比较了两种技术捕集的效果,结果表明气固微萃取技术捕集效果更佳。此外还分析了香烟过滤嘴对清除烟气自由基的作用。 In the paper, we used p-hydroxybenzoic acid (4-HBA) as a trapping agent to trap hydroxyl radicals in cigarette smoke with gas-liquid microextraction and gas-solid microextraction techniques. Compared the effects of two technologies, gas-solid microextraction trap better. In addition, we also analyzed the cigarette filters for clearing smoke free radicals.
