摘 要: | 目的建立气相色谱定量测定水产品中16种有机氯类混合农药残留的方法。方法样品由乙腈提取,以氨基固相萃取柱(Carb/NH_2)净化,经气相色谱检测分析。结果 16种化合物在0.05~1.00mg/L内线性关系良好(r0.998),各有机氯的检出限为0.04~0.31μg/kg(S/N=3)。在加标水平为50、100、200μg/kg时,该方法的回收率为72.6%~115.2%,相对标准偏差为0.6%~7.5%。结论该研究建立的方法选择性好、灵敏度高,适用于水产品中有机氯类农药的多残留痕迹测定。

Abstract: | Objective A method for quantitative determination of 16 kinds of organochlorine pesticide (OCPs) in aquatic prod-ucts by gas chromatography (GC)was established .Methods The sample was extracted by acetonitrile ,purified by Carb/NH2 ,and then determined by GC .Results The linear relations of 16 kinds of OCPs were good at 0 .05 - 1 .00 mg/L(r> 0 .998) .The limit of detection of OCPs was in the range of 0 .04 - 0 .31 μg /kg(S/N = 3) .When the standard levels were 50 ,100 ,200 μg /kg ,the recovery rates were 72 .6% - 115 .2% ,the relative standard deviations were 0 .6% - 7 .5% .Conclusion The method established in this stud-y is applied to the determination of 16 kinds of OCPs in real samples with satisfactory results . |
