Abstract
El presente trabajo forma parte de la línea de investigación sobre tratamiento de aguas residuales que desde hace años se viene desarrollando por el grupo de Catálisis y Procesos de Separación (CyPS) del Departamento de Ingeniería Química y de Materiales de la Universidad Complutense de Madrid. En concreto, el desarrollo de esta Tesis Doctoral se enmarca en el proyecto REMEWATER, financiado por el Ministerio de Economía y Competitividad (CTQ2014-59011-R), cuyo objetivo es la eliminación y posterior recuperación de metales estratégicos. En este contexto, se ha estudiado la adsorción de dos metales estratégicos: Co (II), como ejemplo de metal divalente y Ga (III) como ejemplo de metal trivalente sobre diferentes zeolitas naturales, como la chabazita y la clinoptilolita. Además, se ha sintetizado un material híbrido basado en clinoptilolita/chitosan para evaluar su selectividad hacia Co (II) en adsorción competitiva en sistemas de varios metales divalentes...
