摘要
试样剪碎后置于饱和NaCl溶液中40℃超声处理后，采用100μm聚二甲基硅氧烷（PDMS）作为固相微萃取技术（SPME）装置的固相涂层，采用顶空固相微萃取气相色谱（HS-SPME-GC-MS）法，测定了皮革样品中部分芳香烃（苯、甲苯、乙苯、对-二甲苯和异丙苯）残留。方法给出了相应的检测限量和适用范围，目标化合物的检测限量低于0．001mg／kg，回收率在96．8％～103．7％之间。
It presented the research work on detecting volatile aromatic hydrocarbon residues in leather products according to the limit control of EU 2002/371/EC and European Oko - Tex standard 100. Ultrasonic treatment and 50℃ water - bath was adopted for samples preparation before the headspace solid - phase microextraction （ HS - SPME） were made by fused - silica fiber with 100μm polydimethylsiloxane （PDMS）. Extractions were then directly analyzed by gas chromatography/mass spectrometry （GC/MS）. The detection limit was below 0. 001mg/kg with average recovery between 96. 8% - 103. 7%.
