采用离子选择性电极技术分析了15种牌号过滤嘴香烟烟雾中氟化氢的含量。所分析的香烟,在带过滤嘴和去除过滤嘴情况下,其烟雾含氟量((?)±S)分别为0.236±0.131μg/支(或0.280±0.138μg/g)和0.431±0.167μg/支(或0.517±0.178μg/g)。利用本法分析烟雾的相对标准偏差和回收率((?)±S)分别为3.1%(n=6)和98.1±5.7%(n=5)。结果表明,香烟过滤嘴可过滤烟雾并部分去除所含氟化氢。香烟烟雾所含的氟化氢可能是吸烟导致某些疾病的原因之一。
Ion-selective electrode technology was used to analyze the content of hydrogen fluoride in cigarette smoke of 15 kinds of filter cigarettes. The analyzed cigarettes contained 0.236 ± 0.131 μg / branch (or 0.280 ± 0.138 μg / g) and 0.431 ± 0.167 μg / branch (0.236 ± 0.138 μg / g) respectively, with and without filters (Or 0.517 ± 0.178 μg / g). The relative standard deviations (RSDs) and recoveries (% ± s) of the smoke analyzed by this method were 3.1% (n = 6) and 98.1 ± 5.7% (n = 5), respectively. The results show that cigarette filters filter smoke and partially remove hydrogen fluoride. Hydrogen fluoride contained in cigarette smoke may be one of the causes of certain diseases caused by smoking.
