气相色谱法检测鸡蛋中氟虫腈的残留
|
摘要
建立了气相色谱测定鸡蛋中氟虫腈的检测方法。样品经过乙腈/水提取、HLB固相萃取柱净化、气相色谱外标法测定表明,氟虫腈在0.000 5～0.064 0μg/m L内具有较好线性关系,线性相关系数0.999 85,方法检出限0.6μg/kg,加标回收率73.4%～84.2%,RSD值6.1%～8.6%。该方法前处理简单快捷、灵敏度高、准确性好,能够满足对鸡蛋中氟虫腈残留量的检测需要。
A gas chromatographic method(GC) for determination of fipronil residues in eggs was established. In this method,the samples were extracted with acetonitrile/water,then further cleaned up by HLB solid-phase extraction column. Good linear relationship was obtained in the concentrations of 0.000 5～0.064 0 μg/m L,while the correlation coefficient was 0.999 85. The detection limit of this method was 0.6 μg/kg and the average recoveries was 73.4%～84.2%. The relative standard derivation(RSD) was 6.1%～8.6%. The method is simple,rapid,sensitive and accurate to meet the needs of the analysis,which could be used for the detection of fipronil residues in eggs.
