摘要 将空气中的苯、甲苯、二甲苯用自制活性炭采样管吸附,经二硫化碳解吸,利用OV-101型毛细管色谱柱分离,使用氢火焰离子检测器检测,以标准样品进行定性,以峰面积进行定量。分别对测试方法的灵敏度、精确度、准确度等方面进行了研究,结果表明该方法的主要技术指标符合室内环境空气监测的要求。 Benzene, toluene and xylene in the air was adsorbed by activated carbon, desolated by C82, separated by OV-101 capillary column ,detected by FID, and compared to the standard compounds. The peak area was chosen for quantity. Under some conditions were improved, the accuracy, precision and stability of this method were studied. Results showed that this improved method is suitable for determination of benzenel toluene and xylene in indoor air.
