Supercritical fluid extraction as a clean-up method for the extraction of pesticides from wool wax. A preliminary approach

Abstract

Este trabajo es un estudio preliminar para el desarrollo de un metodo de extraccion de pesticidas directamente de las muestras de cera mediante extraccion con fluido supercritico. La novedad del estudio consiste en la extraccion directa de los pesticidas de la cera de lana cruda sin ninguna limpieza previa, cuando muchos autores han considerado casi imposible la extraccion directa.The work presented is a preliminary study for the development of a method for the extraction of pesticides from wax samples by means of superficial fluid extraction. The novelty of the study is the direct extraction of the pesticides from raw wool wax without any cleanup, as direct extraction has been considered almost impossible by many authors
