Özet:

 

The kinetic parameters for the dehydration of bentonite from Turkey,  KSF and K10 were determined by using dynamic TG techniques.  The Ozawa  method is better for the dehydration of the clay samples than the  first order equation of Coats and Redfern.  The former function  calculates consistently higher activation energies than the latter.   The mean values of the activation energies in the \a range  0.1-0.7, are 56-66 kJ mol-1 in the Ozawa method.
