| Abstract |
| The effect of H-kaolinite on the pH of a dilute suspension of H-montmorillonite
has been studied and the nature of their interaction was examined in relation to their
lattice structure and surface property. A small but gradual decrease of pH of the H-montmorillonite
suspension was observed up to 18% addition of H-kaolinite beyond which
the pH increases rapidly. The titration behaviour is similar to that of HCl-H-clay
system. H-kaolinite was found to interact with H-montmori/lonite due to the electrostatic
attraction between the positive and negative sites of H-kaolinite and H-montmorillonite
respectively. The interaction appears to be independent of the structural peculiarity
of the clay particles but related to their surface area. |
