固相微萃取-毛细管气相色谱法测定水中有机污染物

Analysis of Organic Pollutants Using Solid Phase Micro-extraction/Capillary GC

固相微萃取是一种快速、简便、集萃取浓缩于一体的样品前处理技术,具有分析快速、灵敏度高、无需有机溶剂的优点。用固相微萃取-毛细管气相色谱分析水中甲醇、丙酮、异丙醇、乙醇、乙腈、丙烯腈,检出限可达0.003～0.03mg/L。

Solid phase micro-extraction(SPME),a solvent-free and quick pretreatment method for water-borne organic pollutants,was applied in a study involving analysis of methanol,ethanol,isopropyl alcohol,acetone,acetonitrile and acrylonitrile in water by capillary GC(FID),minimum detection limits ranging 0.003-0.03 mg/L.
