Bousba S., Meniai A., 2014, Removal of Phenol from Water by Adsorption onto Sewage Sludge Based Adsorbent, Chemical Engineering Transactions, 40, 235-240.
The aim of this study is to evaluate the adsorption performances of sewage sludge based adsorbent SSBA for the removal of phenol from water. The SSBA was prepared by chemical activation with H2SO4 in a mass ratio of 1:1, followed by a pyrolysis at 650°C for 1 h under inert atmosphere. Phenol removal by SSBA was investigated using kinetic and equilibrium experiments. The results demonstrate that phenolsorption to the SSBA reached equilibrium at 2 h with the maximum sorption capacity of 26.16 mg.g-1 undergiven experimental conditions (initial Phenol concentration range = 40–200 mg.l-1; adsorbent dose = 5.0 g.l-1 and temperature = 20°C). The phenol removal was high and relatively constant at (pHpKa).The results indicate that the pseudo second order model was suitable for describing the kineticdata. Regarding the equilibrium data, the Freundlich isotherm was fitted well. This study demonstrates that SSBA could be used for phenol removal from water.
