| 摘 要： | 目的建立串联固相萃取-气相色谱法测定马铃薯中肟菌酯残留量的方法。方法捣碎的试样经乙腈浸泡,加入氯化钠,用均质器匀浆提取,C_(18)柱、石墨化炭黑柱和氨基柱三柱联用固相萃取净化,用气相色谱仪电子捕获检测器检测,外标法定量。结果在质量浓度0.01~2.0μg/m L范围内,峰面积与其浓度的线性关系良好,相关系数为0.9995,方法检出限为1×10~(-12) g,最低检出浓度为0.02 mg/kg,分别在0.02、0.20、2.00 mg/kg 3个添加水平进行加标回收试验,平均回收率为81.3%~97.3%。结论该方法简便、快速、准确、重现性好,适用于马铃薯中肟菌酯残留量检测。
