Abstract

Homoionised bentonites were prepared from commercial bentonites with hydrochloric acid. The Atterberg limits and the DTA curves were determined for the homoionised and commercial bentonites. This study shows that DTA can be used as a method for differentiation between clays containing mono- and divalent cations.
