Abstract

The sorptional-structural characteristics obtained from nitrogen (77º K) adsorption izoterms of conventional and competitive intercalated montmorillonite with aluminum oligomers were elucidated, and the optimal conditions for its synthesis were identified. Overall is found that the synthetized adsorbents are a satisfactory thermal stability, its specific surface maintaining highly after calcination on 450º C. The optimization of initial molar ratio OHֿ / Al3+ of utilized oligomeric solutions proves to be an important step in the synthesis process of adsorbents.
