摘要
建立了供水管网中三氯乙醛的吹扫捕集/GC-MS检测方法.吹扫捕集与碱化反应同时进行,三氯乙醛完全快速转化为三氯甲烷,通过检测加碱前后管网水中三氯甲烷的含量,间接计算出管网水中三氯乙醛的含量.方法的线性范围为0～20μg/L,检出限为0.16μg/L,相对标准偏差<5%,平均回收率为90%～100%.
The method for the determination of trichloroacetaldehyde in water by purge and trap-GC /MS and its relevant detection conditions were introduced in this paper.The result of analyzing trichloroacetaldehyde showed that the detection limit was 0.16 μg /L.The RSD（n=7）was less than 5%,the recovery rate was between 90% and 100%.
