Abstract
The chief adsorption characteristics of modified montmorillonite towar d hydrogen chloride, sulfur dioxide, and ammonia have been determined and it has been demonstrated that the adsorbate molecules can penetrat e the stable micropores formed in the mineral structure. A procedure h as been developed for producing semisynthetic adsorbents based on natu ral montmorillonite by replacing the interlayer exchange cations in th e original mineral by oligomeric hydroxoaluminum cations using concent rated aqueous dispersions with a solid:liquid ratio of 1:12.
