Abstract

Background: Due to the stability, water and environmental pollution, and health concerns of phenol compounds, PHENOL REMOVAL is important. For this purpose, the present study evaluated the efficiency of PHENOL REMOVAL of activated carbon derived from MORINGA OLEIFERA pod from aqueous solutions.Methods: In this study, the MORINGA OLEIFERA pod was used as carbon source in activated carbon preparation. The activated carbon preparation protocol included dehydration, debris removal, and thermal activation. After preparation of activated carbon, the effective parameters on phenol ADSORPTION process including solution pH, contact time, initial concentration of phenol, and activated carbon doses were studied. In addition, the obtained data was tested via Langmuir and Freundlich isotherms.Findings: The obtained results showed that the highest phenol ADSORPTION was achieved at neutral solution pH. With increasing or reducing of solution pH, PHENOL REMOVAL efficiency decreased. Moreover, with increasing of contact time from 5 minutes to 840 minutes, PHENOL REMOVAL efficiency improved from 23% to 94%. In addition, with increasing of initial concentration of phenol, PHENOL REMOVAL efficiency had a descending trend. Thus, with the use of 0.5 g/l activated carbon and initial concentration of 7.5 mg/l, PHENOL REMOVAL efficiency was 76%, and at the concentrations of 10 and 15 mg/l, removal efficiency reduced to 71% and 66%, respectively. The obtained results were in line with the Freundlich isotherm and maximum ADSORPTION capacity varied from 6.5 to 7.2 mg/g in the studied initial phenol concentration.Conclusion: The obtained results demonstrated that activated carbon derived from MORINGA OLEIFERA pod had high efficiency in PHENOL REMOVAL from aqueous solutions. With respect to the fact that the MORINGA OLEIFERA is grown in southern Iran and does not have a specific application, the MORINGA OLEIFERA pod could be considered as a low cost source for activated carbon preparation.
