dc.description.abstractLos derrames de hidrocarburos en fuentes de agua son eventos de alta afectación ambiental, lo que conduce al desarrollo de métodos que faciliten la respuesta ante estas eventualidades, donde es prioritario maximizar la selectividad y minimizar los tiempos de recolección. Los materiales porosos con superficie modificada se han presentado como una alternativa para la atención de derrames de hidrocarburos en fuentes de agua, debido a su aplicabilidad como barrera selectiva. En esta tesis se desarrolló una metodología para el uso de espumas de aluminio obtenidas por infiltración de moldes solubles y su alteración superficial por inmersión en solución de ácido dodecanoico, obteniendo un material con características hidrófobas que favorecen su aplicación en procesos de separación de mezclas agua/hidrocarburos. Se obtuvieron probetas de tamaños de poro de entre 425 y 1200 μm, las cuales fueron empleadas en un proceso de separación dinámica de agua/aceite por succión. El material mostró repelencia por el agua y eficiencias de separación superiores al 98%, posicionando al aluminio dentro de los materiales de alto potencial de uso en la obtención de barreras selectivas de fluidos.spa
