Abstract

Background: In recent years, proficient treatment of wastewaters containing RECALCITRANT and toxic compounds such as PHENOL has been a challenge. This study introduced and evaluated an efficient option for treating such wastewater.Methods: This experimental study was performed on PHENOL removal as a RECALCITRANT and toxic compound in aqueous solutions in 2011. The PUMICE stone was collected from a local mine. Collected samples were crushed and granulated using standard sieves (mesh size of 20). CuSO4 was used to modify prepared samples. The chemical compo-sition and the surface area of the modified PUMICE were evaluated using X-ray fluores-cence and N2 gas via Brunauer-Emmett-Teller isotherm and Belsorb software. Different parameters including of pH (3-12), contact time (20-120 min), PHENOL concentration (25- 400 mg/L) and adsorbent dosage (0.25-1 g/L) were examined in a batch reactor.Results: 93.5% of the PHENOL was removed under optimum experimental conditions of pH 3 and a 0.5 g/L adsorbent dose after 60 min contact time. The experimental adsorp-tion isotherm the best fit with Freundlich equation model. The maximum amount of phe-nol ADSORPTION onto modified PUMICE (MP) was 15.8 mg/g.Conclusion: Modified PUMICE is effective adsorbent for the removal of PHENOL from aqueous solution. Accordingly, it is feasible and promise adsorbent for treating polluted PHENOL streams.
