研究了用吹扫-捕集气相色谱法测定自来水中的三氯乙醛含量。水样中的三氯乙醛与碱反应后生成三氯甲烷,三氯甲烷经吹扫-捕集仪富集后,利用DB-5毛细管柱分离后经ECD测定峰面积,利用加碱前后两次测定的峰面积之差来确定三氯乙醛的含量。此方法测定水中三氯乙醛的最低检出限为0.2 g/L,加标回收率为90.6%~96.8%,相对标准偏差（n=6）小于3%。此方法方便快捷,对地表水和自来水中三氯乙醛的有良好的分析效果。

The method for analysis of Trichloroacetaldehyde in water has been developed.Trichloroacetaldehyde in water was concentrated by Purge and Trap Sample Concentrator.It was separated by DB-5 capillary column in GC,and detected by Electrical Conductivity Detector（ECD）.The limit of detection（LOD）was 0.2 ？g/L,the mean recoveries were between 90.6 % and 96.8 % with relative standard deviations of below 3 %.The proposed method was simple,rapid and accurate,suited to drinking water,groundwater.
