Otimização das condições de extração e análise de herbicidas triazínicos com o emprego de cartuchos de extração em fase sólida (SPE) à base de monólitos poliméricos

Abstract

With the development of world agriculture, pesticide production has grown continuously For Pest Control OR Weeds. Dento ESSA class the Most Employee group and one of the triazines, which are in use for control of pre- and post-emerging weeds in various crops. This work aimed at optimizing and extraction conditions of triazine herbicides in Solid phase cartridges employing one Polymeric Monoliths base based on styrene-divinylbenzene. The High Performance Liquid Chromatography, HPLC was used for the evaluation of the Work Developed results. The optimized parameters for an SPE Were: solvent desorption, the volume of the sample and the volume of desorption. The herbicides studied Were atrazine and prometryn, of the triazine class. Recovery Percentage values ranging between 3.55% and 7.16% for atrazine and between 7.83% and 19.09% For a prometryn with total hum pace Analysis 15 minutes with a good resolution of the peaks.
