Özet:

 

In this study, the absorbance measurements were taken for the  bleaching of sunflower-seed oil with wt.  0.3, 0.5, 0.7 and 0.9 % of  clay at 60, 70, 80 and 90°C. Bentonite EY-09 was used as the bleaching  clay.  Since the heat evolved during adsorption (0.33-1.07 kJ  mol-1) was less than 20 kJ mol-1, the forces between the  adsorbent and adsorbate appear to be van der Waals forces, and this  type of adsorption is physical or van der Waals adsorption.  Thus, it  was seen that the Freundlich equation was more applicable than the  Langmuir equation to the experimental adsorption isotherms for the  bleaching of sunflower-seed oil with Bentonite EY-09.
