| 摘 要： | 目的建立检测春笋中吡虫啉、茚虫威、辛硫磷和克百威4种农药的QuEChERS-高效液相色谱-串联质谱法。方法前处理采用QuEChERS方法,乙腈为提取液,N-丙基乙二胺(PSA)为净化剂,结合液相色谱-质谱联用技术,正离子多反应监测(MRM)模式进行检测,外标法定量。结果吡虫啉、茚虫威、辛硫磷和克百威4种农药在0.5～20.0 ng/ml范围呈良好的线性关系,相关系数(r~2)均大于0.991,在4～40μg/kg加标范围内,4种农药的回收率为72.4%～92.8%,精密度为1.5%～9.2%,方法的检出限为0.4μg/kg,定量限为1.2μg/kg。结论建立了适用于检测春笋中吡虫啉、茚虫威、辛硫磷和克百威4种农药的QuEChERS-高效液相色谱-串联质谱法,该方法准确、灵敏、高效、简便。
