摘　　要：本文采用吹扫捕集-气相色谱联用的方法来测定水环境中的汽油类物质。汽油类和示踪剂4-溴氟苯的回收率令人满意,分别在96.8%-101.5%和93.6%-104.0%之间,汽油类检出限为0.1158μg。该方法具有较高的灵敏度、良好的线性关系。且该方法无需预处理,操作简便,无二次污染。In this paper, a method of purge and trap -- gas chromatography was developed to monitor GROs in the water. Both GROs and the surrogate 4--bromofluorobenzene have got good recoveries,which were betueen 96.8%-101.5% and 93.6-104.0%, respectively. The detection limit of GROs was 0. 1158μg. The method was simple and no double pollutions, and thereforn suitable to monitor GROs in the water.
