A study had been carried out to determine the potential use of sewage sludge ash (SSA) as an adsorbent in removing phenol from aqueous solution. Batch kinetics and isotherm studies were implemented to evaluate the effect of initial phenol concentration and contact time of SSA. Results showed that the adsorption capacities of adsorbent (Kf) for phenol decreased from 14.89 mg/g to 0.68 mg/g as initial phenol concentration increased from 0.1 mg/l to 5.0 mg/l. Results revealed that solution with higher initial phenol concentration required longer time to reach equilibrium state. Adsorption capacity of adsorbent (Kf) decreased from 14.89 mg/g to 0.66 mg/g as contact time increased from 240 minutes to 1200 minutes. Adsorption isotherm analysis showed that the experimental data fit Freundlich model in most conditions.
