| Abstract: | 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 operate. |
