| 摘 要： | 建立吹扫捕集/气相色谱/质谱法测定饮用水源地水中三氯乙醛的方法.通过测定不加碱反应水中原有的三氯甲烷以及加碱以后水中的三氯甲烷含量,间接计算出水中三氯乙醛的含量.该方法检出限为0.1μg/L,回收率介于84％～110％之间,相对标准偏差为2.2％～4.8％,能够满足饮用水源地水中三氯乙醛的分析需要.

| Abstract: | The purge and trap/gas chromatography-mass spectrometry method was applied to determine chloral in drinking water.Chloral was converted into chloroform by adding alkaline,and then detected by detector.The concentration of chloral can be determined indirectly by detecting the chloroform.The detection limit was 0.1 μg/L.The RSD(n=6) was between 2.2 % to 4.8 %,the recovery rate was between 84 % to 110 %.The method is simple,accurate,reliable and applicable to the determination of chloral in drinking water. |
