Asphaltenes and Other Natural Surfactants from Cerro Negro Crude Oil. Stepwise Adsorption at the Water/ Toluene Interface: Film Formation and Hydrophobic Effects

The adsorption of asphaltenes and other natural surfactants at the water/toluene interface has been studied here, using both the ring and pendant drop method to measure the interfacial tension (ç). The dependence of ç on the logarithm of the sample concentration (ln C) (represented as the ç(ln C) is...
