Abstract

Introduction: Using agricultural WASTE PRODUCTs (rice husk and rice husk ash) as a cheap, modern, available and mass-produced adsorber for PHENOL from aqueous solution was studied. ADSORPTION in this way seems more economical in comparison with other conventional methods (which are usually costly). Methods: In this descriptive-analytic survey, batch kinetics and isotherm studies were according to various experimental dose and aqueous solution pH. ADSORPTION equilibrium of rice husk and rice husk ash was reached within 6 hours for PHENOL concentration of 150-500 mg/L and 3 hours for PHENOL concentration of 500-1300 mg/L, respectively. Results: Findings show that aqueous solution pH is an important factor in PHENOL ADSORPTION. The ADSORPTION of PHENOL decreases with increasing pH of the solution. Increasing primary PHENOL concentration, increases adsorber ADSORPTION capacity while PHENOL ADSORPTION efficiency shows an inverse trend simultaneously. Isotherm studies revealed that the equilibrium pattern both adsorber systems well foloww the Freundlich model.Conclusion: In reality, results show that rice husk ash is much more effective (98%) than rice husk (44.5%) for PHENOL removal. Therefore, rice husk ash can be used as an efficient and cheap adsorber for removal of organic pollutants (such as PHENOL) from water and wastewater.
