| Abstract: | Chromialumina pillared montmorillonite was prepared using bentonites from Zhejiang Province and Xinjiang Uygar Autonomous Region as starting materials. Pillaring agent solutions were prepared by hydrolyzing chromium and aluminum salt solutions using Na\-2CO\-3 and NaOH as the source of base respectively. The polyoxochromalumina cations were introduced into montmorillonite through a cation\|exchange process and the products obtained were characterized by XRD, thermal analysis, infrared spectroscopy and BET specific surface measurements. The chromialumina pillared montmorillonite obtained has a basal spacing of 2.1 nm and a BET N\-2 specific surface of 216 m\ 2/g. |
