摘要：

In this paper the electrophoretic light scattering (ELS) measurements were performed to characterize changes of the zeta potential, isoelectric point and the particle size of commercial paraffine wax aqueous emulsion Mobilcer C (Exxon Mobil) as induced by simple (1:1) electrolyte (KCl) and by pH of the continuous aqueous phase. The latter information was vital for better understanding of the problem of colloidal stability of the studied system. It was found in this study that the aqueous paraffine emulsion Mobilcer C (ExxonMobil) was destabilized in the pH range of 3.5 to 8.5 for 1x10(-4) M KCl solution and was subjected to partial preferential coagulation. The best stability of the emulsion was found in the pH range of 6 to 12, where zeta potential ranges between -40 to -30 mV
