Abstract

Polycyclic aromatic hydrocarbons (PAH 's) are internationally recognized as one of the most degrading and polluting substances originating from industrial economic cycle. Several international and national environmental agencies have produced extensive literature on the harmful and potentially fatal consequences of human exposure to PAH 's. Various methods have been investigated in the context of remediation ability of PAH 's from the use of absorbent materials . Recently, the use of absorbent materials with micro / nano dimensions has shown potential, mainly due to the high surface area and the possibility of chemical decoration of the surface of these materials. However, most of the research works using this material indicates low regenerative capacity, i.e., the ability to reuse the material for absorbing PAH 's. In this project, remediation ability of silica-based absorbent micro/nanoparticles extracted from biomass will be systematically studied in terms of the method of preparation and surface chemistry decoration. The aim is to achieve low cost absorbent and economically sustainable systems. Moreover, the regenerative capacity will be evaluated from the insertion of these materials in polymeric membranes, a novel approach for the remediation of PAH 's. Besides the regenerative capacity, a systematic study of the transport properties of these membranes HPA 's will be performed . (AU)
