The purpose of this research work was to investigate the effect of adding a polar organic co-solvent, namely ethylene glycol, as well as anionic and cationic surfactants on the zeta potential of solid asphaltene particles dispersed in aqueous 1.0 mM NaNO 3 solutions. In the absence of ethylene glyco
