Currently, the oil scarcity is not only a concern, but crude oil extraction, transportation, and refinement processes have contributed significantly to the contamination of hydrocarbons around the world, and this contamination has mainly occurred because of oil spills that have become a critical issue at the global level. Polycyclic aromatic hydrocarbons (PAHs) from petroleum are internationally recognized as one of the most degrading and polluting substances from the industrial economic cycle. Several international and national environmental agencies have produced extensive literature on the deleterious and potentially fatal consequences of human exposure to PAHs.Various methods have been investigated in the context of the remediation capacity of petroleum and PAHs from the use of absorbent materials. Recently, the use of absorbent materials with micro/nanometric 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 research works using these materials indicates low regenerative capacity, i.e., the possibility to reuse of the material for absorption of PAHs.In this project, remediation capacity of magnetic absorbent nanoparticles based on silica extracted from the biomass will be systematically studied in terms of the form of preparation and superficial chemistry decoration. The objective is to obtain inexpensive and economically sustainable absorbent systems. On the other hand, the regenerative capacity will be evaluated from the insertion of magnetic materials into polymer membranes, an approach to petroleum and PAHs remediation. In addition to regenerative capacity, a systematic study of the transport properties of petroleum and HPAs in these membranes will be performed. (AU)
