| 摘 要： | 研究并建立了环境空气中7种苯胺类化合物经硅胶管吸附、甲醇解吸、气相色谱氮磷检测器检测方法。研究结果显示：当采集10 L气体时,该方法检出限为0.0059-0.0129 mg/m^3（进样量为1.0μl时）。采集样品密闭、低温可保存3 d。该方法可有效提高检出限、精密度,回收率均满足环境监测要求。

| Abstract: | To establish a method of GC detection of 7 Anilines in Ambient air. The anilines vapor in the air is absorbed by silica gel, desorbed by methanol solvent, separated through gas chromatogaphy and detected by nitrogen and phosphorus detector （NPD）. When the 10 L air captured, the detection limit of this method is 0.005 9-0.012 9 mg/m^3 （inject 1.0 μl）. In condition of darkness and low temperature, the sample can be on stability for 3 days. |
