Abstract

The cation exchange capacity (CEC) of clay minerals has been determined by titration of aqueous suspension of clays with hexadecylpyridinium chloride, monitored using surface tension measurements. In order to make the method suitable for an accurate analysis of the CEC of the clays in drilling fluids or in soils, some parameters affecting the CEC determination (e.g. the presence of carboxymethylcellulose, mixing time and measurement device) have been investigated.
