Abstract

Granular Activated carbon (OSAC) which was derived from olive oil industrial solid waste was chemically activated with different concentrations of phosphoric acid. OSAC-materials were evaluated for their ability to remove Phenol from aqueous solution in a batch technique. Adsorption isotherms were determined and modeled with five linear Langmuir forms, namely the Freundlich, Elovich, Temkin, Kiselev and Hill-de Boer models. The experimental data for the Adsorption of Phenol onto OSAM-materials were fitted well with the Langmuir-1 and 2, Freundlich, Kiselev and Hill-de Boer models. Adsorption was carried out on energetically different sites as localized monolayer Adsorption and was an exothermic process. The uptake of Phenol onto OSAC increased in the following order: OSAC-80%> OSAC-70%> OSAC-60%; the maximum Adsorption capacities of Phenol were found to be 114. 416, 125. 628 and 262. 467 mg/g onto OSAC-60%, OSAC-70% and OSAC-80%, respectively. On the other hand, OSAC-80% was used as a good adsorbent for the removal of Phenol and Cd2+ as Co-pollutants from waste aqueous solutions. 80. 25% of Phenol and 50. 66% of Cd2+ can be simultaneously removed by OSAC-80%.
