| 摘 要： | 用丙酮和正己烷（1＋1）的混合溶剂做萃取剂，采用微波萃取的方法提取动物肉类中的9个多氯联苯（PCBs）单体，通过弗罗里硅土和氧化铝净化后，在带ECD检测器的气相色谱上测定。取样量为2g时，多氯联苯（PCBs）在GC—ECD上响应的线性范围为11～100ng／g，研究的样品加标测定范围为11—500ng／g，检出限从5．3—13．3ng／g，平均加标回收率在98．7％-118％。

| Abstract: | Microwave extraction using the mixture of acetone and n - hexane （ 1 ＋ 1 ） as extractant was adopted for analysis of nine polychlorinated biphenyls （PCBs） congeners. After extraction and cleaned by flofisil and alumina, they were determined by GC -ECD. The results showed that when the sample was 2g, the range of linear response on GC -ECD, matrix spike determination range, detection limit and average matrix spike recovery were 11 - 100 ng/g, 11 -500 ng/g, 5.3 - 13.3 ng/g and 98.7% - 118%, respectively. |
