High Performance Determination of Chloroprene,Isopropylbenzene,Tetrachlorobenzene in Surface Water by Purge and Trap-GC/MS
摘要
Abstract
A fast high performance determination of chloroprene,isopropylbenzene,tetrachlorobenzene in surface water were determined by purge and trap-GC/MS.The extraction parameters,such as purge and trap time and programmed temperature were optimized,and determined the best purge time and temperature to improve the relative standard deviations and recoveries of this method.Under the optimized conditions,the results showed that chloroprene and three other compounds were separated from each other,and the liner range was from 0.25 to 4.00 μg/L,and the correlation coefficients of linear equations were from 0.999 0 to 0.9999.The detection limits of the method for three compounds were in the ranges of 0.003～0.006 μg/L.The method was simple,efficient,accurate and precise which was suitable for rapid analysis of three compounds in surface water.Through the testing of water samples from four sources in Shanghai,none of the three compounds were detected.The results showed that the three compounds studied in the paper,such as chloroprene,in the surface water of Shanghai were at low risk.关键词
