摘　　要：采用毛细管柱测定水中9种痕量硝基苯类化合物、二氯甲烷富集水中硝基苯类化合物,以及转相,电子捕获检测器检测,整个分析过程14min,各组分方法检出限达0.003～0.010μg/L,中、低浓度水样各组份的回收率在93.2%～107%之间,相对标准偏差在4.09%～6.05%之间,满足《地表水环境质量标准》(GB3838-2003)中9种硝基苯类化合物的检测要求。Through capillary column,methylene chloride concentration,phase conversion and electron capture detector,we measured 9 kinds of trace nitrobenzene in water.The whole process is about 14 minutes.The detection limit of each component is 0.003～0.010μg/L; the recovery of in low concentrations in water samples in each group is during in 93.2%to 107%,the relative standard deviation is during 4.09%to 6.05%,which conforms to testing requirements of 9 kinds of trace nitrobenzene in surface water quality standards（GB3838- 2003）.
