| Phenol compounds are common contaminants in industrial wastewater and due to their toxicity and carcinogenic properties to human health at low concentrations, have been classified as hazardous pollutants. The purpose of this study was to investigate the removal of phenol from aqueous solutions by aluminum-modified Pumice powder (APP). In order to phenol removal process, three significant variables, including adsorbent dosage (0.1-1 g/L), Phenol concentration (50-250 mg/l) and retention times (5-100 min) were studied. Three dimensional plots demonstrate relationships between the phenol removal efficiency and paired factors (when another factor was maintained at its optimal level), which describe the performance of APP in a batch process. The results show that phenol removal efficiency in aqueous solution affected by three investigated factors. Maximum phenol removal efficiency of more than 99% was achieved at the optimum conditions (APP dosage of 1 g/l, the phenol concentration of 50 mg/l and contact time of 100 mins). Kinetic parameters were also evaluated and modeled using five kinetic models, including the pseudo-first-order equation, second-order equation, the modified Freundlich, the pore diffusion model and the Elovich equation. The best result of experimental adsorption data obtained by means of the pseudosecond- order models. Equilibrium data obeyed the Freundlich and Langmuir isotherm |
