Abstract
This study was focused on the development of a surface alteration protocol for aluminum discs based on the asphaltenes precipitation, to the future development of cellular aluminum treated superficially for the treatment of contaminated water with oil. Roughness tests were developed to guarantee homogeneity of the samples considered. Water and oil contact angles were measured before and after treatment to evaluate variations in the surface affinity of the specimens and it was found that, although there are variations consistent with the increase of the surface hydrophobicity, this is not significant inside the design of experiments proposed within the methodology.
