摘    要:为提高样品分析效率,研究并建立了吹扫-捕集/气相色谱/氢火焰检测器联用同时测定水中1,2-二氯乙烷、苯、甲苯、氯苯、乙苯、对-二甲苯、间-二甲苯、苯乙烯、邻-二甲苯、异丙苯、1,4-二氯苯、1,2-二氯苯、硝基苯、1,3,5-三氯苯、1,2,4-三氯苯、1,2,3-三氯苯、六氯丁二烯17种挥发性有机物的分析方法。结果表明,当进样体积为25.0ml时,最低检出限为0.0034-0.1088μg/L,相对标准偏差为1.8%~6.4%,加标平均回收率为97.6%-105.8%。该方法可快速、简便、准确、高灵敏度的测定水中17种挥发性有机物,并适用于饮用水和地表水中挥发性有机物的测定。

关 键 词:吹扫-捕集  气相色谱  测定  挥发性有机物

Abstract:In order to increase analytical efficiency of samples,the simultaneous analytical method of seventeen kinds of volatility organic compounds(VOCs) in water by purge and trap - gas chromatography/FID has been established.The seventeen kinds volatility organic compounds(VOCs) are 1,2 - dichloroethane,benzene,toluene,chlorobenzene,ethylbenzene,P-xylene,M-xylene, styrene,O-xylene,isopropylbenzene,nitrobenzene,1,4 - dichlorobenzene,1,2- dichlorobenzene,1,3,5 - trichlorobenzene,1, 2,4- trichlorobenzene,1,2,3- tric...
Keywords:purge and trap  gas chromatography  determination  volatility organic compounds(VOCs)  water
