Abstract:

 


The acid activation of
bentonite from Middle Anatolia, consisting of mostly montmorillonite, with a
hot solution of H2SO4 with different concentrations was
carried out. SEM images, nitrogen sorption isotherms and FTIR spectra were used
to examine the structural changes of the bentonite with acid activation. Acid-base
titration method was applied to determine the surface acidities. The
characterization results indicated that the acid activation caused considerable
increases in the surface area and pore volumes by changing both the morphology and
surface properties. The increase of the acid strength resulted in enhancement
both in the surface area and acid sites up to 2 M concentration. For both Lewis
and Brønsted acidities, significant increases occurred in addition to H-bonding
to the structure.
