| Abstract: | A detection method of purge and trap combined with gas chromatograph/mass spectrometry(P&T-GC/MS)for 13 kinds of common volatile organic contaminants in drinking water was established.The method detection limit(MDL) was 0.041~1.08μg/L,and the average recovery rate of the method was 80%~120%.Under this a wide linear range and a good precision was performed.This analytical method was accurate as well as fast,which could detect 13 organics simultaneously,and also shortened the analytical cycle greatly.Besides,this method was used to detect the drinking water in one city. |
