Abstract—A continuous fixed bed study was carried out by
using granular activated carbon produced from olive stone for
the removal of phenol from aqueous solution. The effects of
initial phenol concentration (40-250 mg/l), feed flow rate
(2.2-8.4 ml/min)and activated carbon bed depth(5-20 cm) on the
breakthrough characteristics of the adsorption system were
determined.The obtained results showed that the adsorption
capacity increases with the bed depth and the initial
concentration and it decreases at higher flow rate.Three models
namely Clark, Thomas, and Yoon - Nelson were employed to
predict the breakthrough curves and to determine the
characteristic parameters of the column useful for column
design.These models fitted well the adsorption data with
coefficient of correlation R2>0.9 at different conditions. The
activated carbon from olive stone was shown to be suitable
adsorbent for adsorption of phenol using fixed bed adsorption.
