Interaction of Oleate Molecules on Sillimanite and Garnet minerals.

Vijaya Kumar , T V and Prabhakar, S and Bhaskar Raju, G (2001) Interaction of Oleate Molecules on Sillimanite and Garnet minerals. In: Advances in surface science and engineering, 21-23 February, 2001, Chennai.



Adsorption of oleate on sillimanite and garnet was studied using electrokinetic measurements. Both the systems exhibit a characteristic shift in iep by increasing the concentration of oleate in solution. This shift in iep has been quantified in terms of specific interaction between the surface sites and oleate molecules. The shift in iep was estimated separately for both the systems using the equation derived on the basis of electrical double layer theory. The specific free energy of adsorption was estimated to be 7.94 kcal/mole for sillimanite-oleate system and 7.49 kcal/mole for gamet-oleate system.
