摘　　要：本文采用固相萃取柱对水样进行富集前处理,建立了气相色谱-质谱法同时测定地表水中苯胺、2-氯苯胺、3-氯苯胺、4-氯苯胺、4-溴苯胺和3-硝基苯胺残留的方法。6种苯胺类化合物在3.00~200μg·L^(-1)浓度范围内线性关系良好,水样的加标回收率为87.1%~104.3%,相对标准偏差为1.9%~4.2%。本方法操作简便,灵敏度和准确度高,检出限低,满足水中多种苯胺类化合物残留的分析。A method for simultaneous determination of aniline,2-chloroaniline,3-chloroaniline,4-chloroaniline,4-bromoaniline and 3-nitroaniline residues in surface water by gas chromatography-mass spectrometry was established by using solid phase extraction column as the pretreatment for enrichment of water samples.The linearity of the six aniline compounds was good in the concentration range of 3.00~200μg·L^(-1).The recoveries were 87.1%~104.3%and the relative standard deviations were 1.9%~4.2%.The method has the advantages of simple operation,high sensitivity and accuracy,low detection limit,and meets the requirements for the analysis of aniline residues in water.
