Stability of kaolinite dispersions in the presence of sodium and aluminum ions

►Theoretically Explained stability of kaolinite dispersions based on the DLVO theory. ►Presented the results of adsorption of hydrolyzed aluminum species on kaolinite. ►Found that kaolinite coagulation was stronger in the presence of NaCl than of AlCl3. ►Found maximum aluminum adsorption density on kaolinite coincided with PPT.
