چكيده فارسي :
In this study dynamic adsorption of methylene blue MB on two types of activated carbons AC, produced from walnut shell and coconut sell was investigated using a lab scale fixed bed adsorption column. Effects of three fundamental parameters in dynamic adsorption process i.e., initial feed concentration, flow rate and active bed length were studied in the light of the breakthrough curve analysis. MB removal percentage and bed adsorption capacity of the two types of ACs were calculated and compared to evaluate the column adsorption performance of the adsorbents. The average values of MB removal percentage for coconut shell and walnut shell-based ACs were obtained as 42.08% and 41.78%, respectively. The results were comparable however, a little better for the coconut shell-based AC due to its higher surface area in comparison with the walnut shell-based AC. On the other hand, walnut shell-based AC exhibited superior bed adsorption capacity 0.686 mg per g compared to that of the coconut shell-based AC 0.534 mg per g, owing to its lower density and larger pore size
