摘　　要：快速气体分析仪在环境突发事故中起着重要作用,本研究利用ZNOSE快速气体分析仪,对苯胺气体标准样品以及模拟实际大气样品的气体进行分析,探讨了污染事故中苯胺快速测定方法,并对快速气体分析仪在苯胺污染事故中的适用性进行评定。测定结果表明该方法对苯胺气体样品具有高的灵敏度和快速响应,并对检出物具有非选择性和可变检出限。采在事先做好样品标准谱图的情况下,用ZNOSE快速气体分析仪可以在短时间内确定大气环境中的苯胺及其浓度,能满足环境污染实时监测的需求,尤其是处理环境污染事故。The fast-response portable gas analyzer plays a key role in determination of pollutants during environmental emergency events.ZNOSE（GC /SAW） is a fast gas chromatography analyzer with surface acoustic wave（SAW） detector.This study utilized ZONES to determine the standard samples and gas samples by simulating the real atmospheric conditions,and develop a method to quantitatively determine aniline in the atmosphere.The results show that ZONES responses fast and have high sensitivities for aniline.With pre-prepared standard curve,ZONES can quickly identify the atmospheric aniline and determine its concentration.This meets the needs of environmental monitoring,especially,for the environmental emergency monitoring.
