摘要: 以聚丙烯腈（PAN）和二氧化硅（SiO₂）纳米粒子的混合溶液为纺丝溶液，采用静电纺丝技术制备具有高吸附性能的新型PAN-SiO₂疏水性复合纤维膜，对香烟燃烧产生的烟气进行富集，用甲醇作为洗脱溶剂，对待测组分进行洗脱，并使用高分辨串联质谱技术进行测定。实验结果表明，通过调控PAN和SiO₂纳米粒子的浓度，优化静电纺丝参数，得到对小分子有机化合物吸附性较强的纤维膜。对所收集到的烟气进行质谱测定，在正离子模式下，检测到的主要成分有尼古丁、丙酮、苯乙烯、丙烯醛、异戊二烯、丙烯腈等21种小分子有机化合物；在负离子模式下，检测到的主要成分有水杨酸、苹果酸和乳酸等6种有机酸。同时，对烟气中的主要有害成分尼古丁进行定量分析，方法的检出限为0.071 ng/L，定量限为0.236 ng/L。

Abstract: A new method was proposed for analysis of the organic compounds in cigarette smoke by high resolution Orbitrap mass spectrometry based on polyacrylonitrile-silica (PAN-SiO₂) nanofiber membrane extraction and methanol elution. Hydrophobic PAN-SiO₂ nanofiber membrane which was used to enrich small molecular organic compounds in cigarette smoke was prepared by the technology of electrospinning. Several parameters including the concentrations of PAN and SiO₂ nanopartical, elecrospining voltage, needle aperture and flow rate of spinning solution were optimized. Under the optimal conditions, a PAN-SiO₂ nanofiber membrane with good adsorption performance and great physical strength was obtained. A total of 21 compounds including acetone, styrene, acrolein, isoprene, and acrylonitrile were identified by analyzing the cigarette smoke with Orbitrap MS spectrometry in the positive ion mode. Six organic acids including salicylic acid, malic acid and lactic acid were detected in negative ion mode. The limits of detection and quantification for nicotine were 0.071 ng/L and 0.236 ng/L, respectively.
