摘要
通过对氯苯在Tenax GC上的富集和热解吸效果的研究,建立了大气中痕量氯苯的分析方法.该方法操作简便、快速、重现性好,当大气采样量为5L时,最低检出浓度为0.001mg/m^3.方法可用于大气中痕量氯苯的测定.
A rapid and reliable gas chromatographic method for determining trace phylch-loride in air is presented. The analytical procedures are as follows, absorption with Tenax GC, heat decomposition at 180 C, separation with 5% OV-17 colume chrc-matography and determination by FID. The detection limit is 0.001mg/m3 when the quantities of air are 5 liters. The proposed method has been applied to determine air samples with satisfactory result.
