Comment: |
assumed that the edge sites of montmorillonite are the locations for reactive surface sites. These sites represent 10% of the total available surface area [TPB98a]. Therefore, the site density was decreased to 0.23 sites per nm² when calculating the aluminol and silanol site concentrations; assumed Al:Si ratio of 0.83 [WZ88]; protolysis constants from [T95] |
