摘要
毛织物试样剪碎后置于饱和NaCl溶液中经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,通过顶空固相微萃取气相色谱（HS-SPME-GC-MSD）法测定了织物样品中的9种挥发性有机化合物（VOCs）.该方法给出了相应的检测限量和适用范围,织物样品中9种VOCs的检测限量均低于0.001 mg/kg,回收率在96.8%～103.7%之间.
This paper presented the resear6h work in detecting volatile organic compounds （including 9 compounds） in wool fabrics according to the limit control of European Oko-Tex standard 100 on VOCs. Ultrasonic extraction and 40℃ water-bath was adopted for samples treatment before the headspace solidphase microextraction （HS-SPME） were made by fused-silica fiber with 100 μm pelydimethylsiloxane （PDMS）. Extraction was then directly analyzed by gas chromatography/mass spectrometry （GC/MS）. The paper also gived application range for safe assessment of wool fabrics in consumption and dry cleaning. The limits of detection were below 0.001 mg/kg with average recovery between 96.8 % - 103.7 %.
