摘　　要：采用气相色谱(μ-ECD)开发了高效氯氟氰菊酯在万寿菊上的残留分析方法,利用QuChERS前处理方法,经乙腈提取、PSA净化,氮气吹干后用正己烷定容,外标法定量。高效氯氟氰菊酯在万寿菊中的添加回收率为97%~99%,相对标准偏差在4.0%~8.5%。笔者建立了万寿菊中高效氯氟氰菊酯气相色谱残留分析方法,能够满足万寿菊样品中的高效氯氟氰菊酯的定量分析,并对万寿菊高效氯氟氰菊酯最终残留量进行了检测,样品中的高效氯氟氰菊酯均未检出。The residue analysis method of lambda-cyhalothrin in marigold was developed by gas chromatography(μ-ECD).The samples were prepared by QuEChERS method.It was extracted by acetonitrile,then purified by PSA,dried by nitrogen.After that,it was brought to volume by n-hexane,and quantified by external standard method.The recoveries of lambda-cyhalothrin in marigold were between 97%and 99%,with the relative standard deviations were from 4.0%to 8.5%.The gas chromatography method for the determination of lambda-cyhalothrin residue in marigold was established,which could meet the requirements of the analysis of lambda-cyhalothrin in marigold samples.The final residue of lambda-cyhalothrin in marigold was analyzed,and no lambda-cyhalothrin was detected in the sample.
