For a given clay mineral type, the adsorption sites and condensation capacity increased with increasing clay content. At a given clay content, the number of adsorption sites was in the order of montmorillonitic samples (ML)>mixed clay samples (MX)>kaolinitic samples (KA), and the condensation capacities of ML and MX were lower than that of KA.
