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。

摘  要:
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.
