摘要
本文采用具有分离手段的薄层层析,选择合适的展开剂,经分离后,分别刮下溴乐乳油中溴氰菊酯和乐果斑条,采用紫外分光光度法在波长276纳米处进行嗅氰菊酯含量测定;采用化学溴化法进行乐果含量测定。该法简便、准确可靠、重复性好,可作为卢品质量位制和检测方法。
In this paper,a procedure to separate the mixtureof decametbrin and dimethoate was descriped.The sample wasdevcloped by a developping agent on a silican GF_(254).Thestripes of decamethrin and dimethoate were scraped respec-tively and the solution of scraped samples were analvsed hy UV-spectrophotorneter at 276nm,The contract of dirnethoatewas determined bv bromination of6imet6oate.The method hasgood accuracy,reliability and exellent reproducibility and easy to o[perate.
