摘要
目的:建立一种同时测定水中9种挥发性卤代烃、3种硝基苯类和5种氯苯类物质的固相微萃取-气相色谱方法。方法:选用100μm PDMS纤维,恒温20℃,稳定的磁力搅拌萃取15 min,带ECD检测器的毛细管气相色谱分离分析。结果:该方法精密度良好(RSD为1.21%～7.36%),加标回收率为75%～130%。结论:该方法实现了9种挥发性卤代烃、3种硝基苯类和5种氯苯类物质的同时测定,具有快速、准确和方便等优点。
Objective：To establish an analytical method for the simultaneous detemination of volatile halocarbon,nitrobenzene compounds and chlorobenzene compounds in water samples.Methods：The extraction was carried out at 20℃ for 15 minutes using 100 μm PDMS fiber as the solid phase and then used gas chromatography with a electron capture detector（GC-ECD） to analyze.Results：The method showed good precision（RSD 1.21%～7.36%） and the recovery rate was 75%～130%.Conclution：This method is simple,fast,precise,sample-efficient and solvent-free.
