摘要: 比较优化了气相色谱-串联质谱测定花生油中农药残留的提取方法,评估了C18、乙二胺-N-丙基硅烷(PSA)、C18与氧化锆共同键合物(Z-Sep+)、增强型脂质去除产品(EMR-Lipid)4种分散吸附剂的净化效果。结果表明,样品直接使用乙腈提取时,回收率最高;增加提取溶剂与样品的比例时,回收率提高。PSA、Z-Sep+与EMR-Lipid均能一定程度上降低基质对检测的干扰,但每种吸附剂都有其特点,需根据被检测化合物的实际情况进行选择。

Abstract: The extraction methods for the determination of pesticide residues in peanut oil by gas chromatography-tandem mass spectrometry (GC-MS/MS) were compared and optimized. The purification effects of four dispersive adsorbents including C18, primary secondary amine (PSA), C18 zirconia-coated silica(Z-Sep+) and Enhanced Matrix Removal-Lipid(EMR-Lipid) were evaluated. The results showed that the recovery was the highest when the sample was extracted directly with acetonitrile. When the ratio of extraction solvent to sample was increased, the recovery rate was increased. PSA, Z-Sep+ and EMR-Lipid can reduce the interference of the matrix to a certain extent, but each adsorbent had its own characteristics and needs to be selected according to the actual situation of the detected compounds.
