Abstract

Método para la extracción y concentración simultaneas de compuestos de fases líquidas utilizando membranas microporosas. En este método la extracción y concentración de compuestos líquidos se realiza simultáneamente utilizando para ello un agente de extracción selectivo hacia el/los solutos que se quieren extraer. Este agente de extracción forma con el/los solutos complejos reversibles que se liberan en la etapa de concentración de modo que el agente de extracción es regenerado para ser utilizado de nuevo en el proceso. Ambas etapas de extracción y concentración se realizan utilizando membranas microporosas donde el contacto entre las fases se realiza en los poros de las fibras que se encuentran en el interior del módulo, de modo que se evita la dispersión de las fases y por tanto su posterior separación. Además se debe aplicar una ligera sobrepresión a la fase por la cual las fibras no están preferentemente impregnadas con objeto de evitar la dispersión de las fases. El funcionamiento delsistema puede ser en continuo, discontinuo o semicontinuo.
