目的对3种常见家卫杀虫产品的部分质量检测方法进行探讨,为控制这几种卫生杀虫剂的质量控制提供依据。方法气相色谱内标法。结果杀虫气雾剂的2种样品处理方法的重现性RSD分别是1.68%~2.00%和0.49%~0.94%,盘式蚊香的2种热贮方法的降解率分别是9.24%和2.65%,电热蚊香片的2种样品抽取方法的含量测定RSD是1.81%和0.24%。结论杀虫气雾剂有效成分含量测定喷出取样配制法(方法2)优于剖罐取样配制法(方法1);盘式蚊香粉末密闭热贮法优于市售包装热贮法;电热蚊香片有效成分含量测定5片抽取法优于单片抽取法。
Objective To explore the quality control methods of three common home insecticide products and provide the basis for controlling the quality control of these kinds of insecticides. Methods Gas chromatography internal standard method. Results The reproducibility RSDs of the two insecticidal aerosol samples were 1.68% -2.00% and 0.49% -0.94%, respectively. The degradation rates of two heat storage methods of tray mosquito were 9.24% and 2.65% , And the content RSDs of the two sample extraction methods of the electric mosquito coils were 1.81% and 0.24%. Conclusion The insecticidal aerosol composition of the active ingredient is better than the method of Sampling sampling (Method 1) Determination of the active ingredient content 5-piece extraction method is better than the single-chip extraction method.
