Adsorption of phenol from aqueous solutions using incinerated sewage sludge
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 th...

| Ringkasan: | 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. |
