摘要
目的 建立测定蚊香、电热蚊香液和电热蚊香片中6种有效成分(四氟醚菊酯、四氟苯菊酯、四氟甲醚菊酯、富右旋反式烯丙菊酯、炔丙菊酯和氯氟醚菊酯)和2种禁用成分(仲丁威和八氯二丙醚)含量的研究。方法 采用气质内标法。结果 该方法测定6种有效成分和2种禁用成分的回收率为74.5%~94.3%。精密度试验显示浓度测定的标准偏差为1.72%~4.55%和峰面积测定的标准偏差为0.97%~2.44%。结论 该方法分离度好、精密度高、灵敏度高、专属性强且操作简单快速。
Objective To establish a method for determination of six active ingredients(tetramethylfluthrin,transfluthrin,dimefluthrin,rich-d-transallethrin,prallethrin,and meperfluthrin)and two prohibited ingredients(fenobucarb and octachlorodipropyl ether)content in mosquito coils,electrothermal vaporizing liquid and electrothermal vaporizing mats.Methods A qualitative and quantitative analysis method utilizing internal standard method of gas chromatography-mass spectrometry was employed.Results The method for six active ingredients and two prohibited ingredients determination showed the recovery rates between 74.5%and 94.3%.The precision test displayed standard deviation in concentration between 1.72%and 4.55%,between 0.97%and 2.44%in peak area.Conclusion The developed method had advantages in good separation,perfect precision,high sensitivity,strong specificity and simply fast operation.
