Effect of Zeta Potential on Phase Separation of Sesame Residue Colloidal System

Abstract

Abstract: The aim of this study was to study the correlation between zeta potential and coagulation of sesame residue colloidal system. The zeta potential and particle size of the system were varied by varying the pH and adding a certain concentration of aluminum ions. The zeta potential of sesame residue colloidal system was nearly zero when the pH was 3.0 or the aluminum ion concentration was 0.02 mol/L. The zeta potential of the system was zero at its isoelectric point and under this condition, the system revealed the highest ease of coagulation and maximum size of colloidal particles.

Key words: sesame residue, zeta potential, pH, aluminum ion solution, separation of solid and liquid phases
