| 摘 要： | 建立了一种液-液小体积萃取GC-MS快速测定地表水中氯苯类化合物的分析方法。该方法具有操作简单快速、适用性广和试剂用量很少等特点。当萃取试剂用量为2ml时(约为一般常规液-液萃取用量的数十分之一),萃取富集效率可达300~500倍,回收率为93%~98%,相对标准偏差为4%~8%,检出限为0.1~0.3μg/L。

| Abstract: | This paper developed a liquid-liquid small volume extraction (LLSVE) method combined with gas chromatography-mass spectrometry for the rapid determination of chlorobenzenes in surface water. The method is simple and fast. Only 2ml extraction solvent is used. The enrichment factor can be 300～500. The recovery rate is in the range of 93%～98%,RSD in the range of 4%～8%,and the detection limit in the range of 0.1～0.3μg/L. |
