摘要
采用小型释放舱释放-Carbosieve^TM Sill＋Tenax TA复合吸附剂捕集-热脱附-GC／MS联用技术，可同时测定纺织铺地物中多种单体和总芳香族化合物以及TVOC（总挥发性有机物）的动态释放量，其回收率为93．5％-105．1％，精密度≤6．43％，9L采样量时最低定量限为0．2μg／m^3。文中研究了测定纺织铺地物中挥发性有机物的复合吸附剂与吸附特性，标准样品吸附管制备，热脱附与GC／MS的工作参数以及影响因素和数据处理等技术要点。
The technical points in determinating of volatile organic compounds from textile floor coverings were studied, including the complex adsorbent and its adsorption character, adsorption tube preparation for standard solution, thermal desorption and operation parameters and method characters of GC/MS, and data analysis. It was found that the combined technique of small scaled emission chamber- CarbosieveTM Sill ＋ Tenax TA adsorbent-thermal desorption-GC/MS, could determine emission rates and emission phenomena of various volatile organic compounds ,total aromatic hydrocarbons and total volatile organic compounds in textile floor coverings. In this method, the recovery percent and precision degree were in the range of 93.5% -105.1%, and the relative standard deviate was less than 6.43%. The limits of quantification for 9L sampling amount was 0.2 μg/m^3.
