Abstract
FROM the amount of aluminium hydroxide adsorbed by kieselguhr (diatomaceous earth) and from the resulting electrokinetic potential (£) of the particles, as shown by their movement in an electric field, Prof. E. C. C. Baly and Mr. W. P. Pepper conclude that aluminium hydroxide is first adsorbed as a uni-molecular layer giving a £-value of 75-4 millivolts. This layer is then able to adsorb a second molecular layer, resulting in a drop in the value of £ to 61-2 mv.
