| dc.description.resumo | This publication reports the adsorption of crude oil on vermiculite samples, expanded and hydrophobized with carnauba (CoperníciaCerífera) wax. The adsorption studies were performed by using columns filled with the vermiculite matrices and by dispersion of the vermic-ulite samples in an oil–water (50 ppm of oil) emulsion. The hydrate vermiculite exhibits a very low adsorption capacity against crude oil. Onthe other hand, anhydrous (expanded) and hydrophobized matrices show a high adsorption capacity. The 10% hydrophobized matrix show a50% increased adsorption capacity, in comparison with the expanded one. For adsorption performed in the water–oil emulsion, saturation ofthe solid hydrophobized matrix is achieved after 60 min. The hydrophobized samples exhibit adsorption factors in the 0.7–1.0 range | pt_BR |
