吸附-热解吸法与气相色谱-质谱法联用测定蚊香烟雾中的有机化合物

Determination of Organic Compounds in the Smog of Mosquito-Repellent Incense by Adsorption-Thermal Desorption-GC/MS

摘要: 利用吸附-热解吸法与气相色谱-质谱法联用，对两种固体蚊香烟气中的有机成分进行定性和半定量分析。在两种固体蚊香烟气中共检测出52种挥发性成分，包括酚类、醇类、醛类以及脂肪烃和芳香烃等多种化合物，其中的部分化合物对人体有毒害作用。蚊香A烟气中含量较多的成分为右旋烯丙菊酯(30.06%)、1,6-脱水-β-D-吡喃葡萄糖(19.4%)和甘菊环(13.9%)等；蚊香B烟气中含量较多的成分为1,6-脱水-β-D-吡喃葡萄糖(24.4%)、甘菊环(14.4%)和正十四烷(5.91%)等。

Abstract: The organic components in the smog of mosquito-repellent incense were analyzed qualitatively and semi-quantitatively by-adsorption-thermal desorption with gas chromatography-mass spectrometry. 52 kinds of compounds are identified in two kinds of solid mosquito-repellent incenses, including phenolic compounds, alcohols, aldehydes, aliphatic hydrocarbons, aromatic hydrocarbons and so on. Some compounds are poisonous to people’s health. The principal components in the smog of mosquito-repellent incense A are allethrin(30.06%), 1,6-Anhydro-β-D-glucopyranose(19.4%), azulene(13.9%), while the principal components are 1,6-Anhydro-β-D-glucopyranose(24.4%), azulene(14.4%), tetradecane(5.91%) for the mosquito-repellent incense B.
