气相色谱-质谱法测定水中的多氯联苯

Determination of Arochlors in Water by GC-MS

采用正己烷萃取法提取水中的多氯联苯系列4种混合物Aroehlor1242、Arochlor1248、Arochlor1254、Arochlor1260,萃取溶液用气相色谱-质谱法进行测定,方法检出限为0.01μg/L,加标回收率在83.5%～96.4%之间,RSD5.3%～10.2%。

Arochlors in water were cxtracted by Hexyl hydride. It finally analyzed with GC-MS. The recovery was between g3.5 %-96.4 %, the detection limit is 0.01 μg/Land RSD was 5.3 %-10.2 %.
