Abstract

In this study, ammonium (NH4+) removal from aqueous media was investigated by using bentonit clay. Different concentrations of ammonium ion adsorption from aqueous solutions were examined at a room temperature. Adsorption data were applied to Langmuir and Freundlich models. In addition, the experimental results of adsorption applied to thermodynamic equations of free enthalpy of adsorption process, enthalpy and entropy values were found. Thus, whether voluntary and adsorption effects of temperature on adsorption or not was investigated. In addition, raw and treated clay ammonium (NH4+-bentonite) characterization of samples were established by using thermal analysis and infrared (IR) techniques.
