ACID ACTIVATION OF MONTMORILLONITE

Abstract
A Pembina montmorillonite clay has been activated with sulphuric acid at various dosages by the conventional wet process and by the new "dry" process. The products are compared with respect to the fractions of the metal ion components remaining after leaching, the hydrated silica content, the bleaching capacity, and the B.E.T. nitrogen and water surface areas which they exhibit. Surface areas were also determined after calcining the products invacuo. The surface areas are discussed with reference to the removal of metal ions occupying octahedral lattice sites in a model clay particle.
