FUNDAMENTAL STUDY OF CLAY: IV, SURFACE AREA AND ITS EFFECT ON EXCHANGE CAPACITY OF KAOLINITE*

Abstract

A bstract Six monodisperse fractions of kaolinite were prepared, and the exchange capacity was determined from the viscosity relations on additions of NaOH to the electrodialyzed fractions. A linear relationship is shown to exist between the surface area and the base‐exchange capacity for all of the sizes studied.
