Removal of ammonium ion from aqueous solution by natural Turkish (Yildizeli) zeolite for environmental quality.
J Hazard Mater. 2007 Mar 06; 141(1):258-63.JH

Abstract

The purposes of this study were to investigate the removal efficiency of ammonium (NH(4)(+)) ion from aqueous solution using the natural Turkish (Yildizeli) zeolite and to characterize equilibrium isotherms. Experiments were carried out using batch method as a function of the solution pH, shaking time, dosage of adsorbent, and temperature. All these factors affected NH(4)(+) ion removal from aqueous solution. Equilibrium modelling data were fitted to linear Langmuir and Freundlich models. Dubinin-Redushckevich (D-R) isotherm was applied to describe the nature of ion exchange of NH(4)(+) and found that it occurred physically. Thermodynamics parameters such as change in free energy (DeltaG degrees), enthalpy (DeltaH degrees) and entropy (DeltaS degrees) were also calculated. These parameters confirmed that ion exchange of NH(4)(+) by the zeolite was feasible, spontaneous and exothermic in nature. Based on the results, it can be concluded that the natural Turkish (Yildizeli) zeolite is suitable for the removal of NH(4)(+) ions in wastewater treatments and agricultural purposes to in terms of sustainability of environmental quality.
