摘要
采用加标回收方法检测分析氯氰菊酯、联苯菊酯、溴氰菊酯、氰戊菊酯、腐霉利、抗蚜威、三唑磷、氯唑磷、甲拌磷、乐果10种农药对韭菜、芹菜残留检测结果的样品浓度与回收率分布关系,显示加标回收率在10%~200%。应用基质匹配法、内标法质控处理,校准调控后的加标回收率在韭菜中为93.2%~103.7%,RSD为1.6%~7.7%;芹菜中为87.2%~100.3%,RSD为2.1%~9.6%。对照《实验室质量控制规范食品理化检测附录F》(GB/T 27404—2008),检测结果符合技术要求。
The distribution relationship between sample concentration and recovery rate of cypermethrin,bifenthrin,deltamethrin,fenvalerate,procymidone,pirimicarb,triazophos,isazofos,phorate and dimethoate on leek and celery was analyzed by standard addition recovery method.The recoveries ranged from 10% to 200%.Matrix matching method and internal standard method were used for quality control,recovery rate after calibration and regulation were 93.2%-103.7%,RSD was 1.6%-7.7% in leek and 87.2%-100.3%,RSD 2.1%-9.6% in celery.Comparing with Laboratory Quality Control Regulations Food Physical and Chemical Testing Appendix F(GB/T 27404—2008),the test results met the technical requirements.
