摘　　要：采用毛细管气相色谱法同时分离测定水中11种氯苯类化合物。用DB-23毛细管柱分离,电子捕获检测器检测,方法线性关系良好,水中氯苯类的最低检出限分别为:二氯苯0.74μg/L^0.89μg/L,三氯苯0.17μg/L^0.21μg/L,四氯苯0.07μg/L^0.11μg/L,五氯苯0.04μg/L、六氯苯0.02μg/L,加标回收率在83.5%~101%之间,RSD在1.4%~5.2%之间。A method is for 11 kinds of chlorobenzenes determination in water samples which separated by DB -23 fused silica capillary column and detected with GC -ECD. The linear relation between instrument responds and calibration standard was excellent. The limits of detection of dichlorobenzenes in water sample were 0.74 μg/L- 0. 89 μg/L respectively, trichlorobenzenes 0. 17 μg/L- 0. 21 μg/L, tetrachlorobenzenes 0.07 μg/L -0. 11 μg/L, pentachlorobenzene 0, 04 μg/L and hexachlorobenzene 0.02 μg/L. The recovery range was between 83, 5% - 101% , RSD 1,4% -5.2%.
