Abstract
Adsorption studies for phenol removal from aqueous solution onto commercial
Powdered Activated Carbon were carried out. Batch kinetics and isotherm studies
were carried out under varying conditions of contact time, initial phenol concentration,
adsorbent dose and pH. The adsorption of phenol increases with increasing initial
phenol concentration and decreases with increasing the solution pH value. The
equilibrium data in aqueous solutions was well represented by the Langmuir and
Freundlich isotherm models. Kinetics of adsorption followed a first order rate
equation. The studies showed that the Commercial Powdered Activated Carbon
can be used as an efficient adsorbent material for the removal of phenolics from
water and industrial wastewater.
