RI 7048 Zeta Potential And Pendulum Sclerometer Studies Of Granite In A Solution Environment

The electrokinetic (zeta) potentials of a charcoal granite in an aluminum chloride (AlCl3) solution and in an oleylanunonium acetate (C18H35NH3+ -OCOCH3) solution have been correlated with the specific damping values as measured by the pendulum sclerometer. This investigation shows that the pendulum specific damping attains a minimum at the isoelectric point for the charcoal granite-aluminum chloride and charcoal granite-oleylammonium acetate systems, and thus indicates that the penetration of the diamond points is a maximum at the isoelectric point.
