- Abstract
Cr and Cr + Al intercalated montmorillonites and their adsorption activity with respect to various adsorbates have been studied. The results of X-ray phase analysis showed that for the Logon bentonite sample, the value of the basal reflection d001 is about 12.3 Å. For Cr and Cr + Al intercalated materials, a shift of the d001 reflection towards a smaller angle is observed, which indicates an increase in the basal distance and intercalation efficiency and its values are 17.5 and 19.8 Å, respectively. A structural change in montmorillonite as a result of pillaring leads to an increase in its textural characteristics and adsorption activity with respect to polar and nonpolar molecules. The textural characteristics of mixed chromium-aluminum intercalated montmorillonite, calculated from the adsorption of nitrogen, hexane and toluene, are much higher compared to the characteristics of a sample of chromium intercalated bentonite.
