Abstract

This paper assesses the potential of magnetically modified zeolite (MMZ) for ammonia removal from aqueous solution. The effects of relevant parameters such as contact time, pH and initial ammonia concentration were examined. The results show that ammonium ion removal by MMZ occurs rapidly within the first five minutes, pH has an effect on ammonium ion removal efficiency, and the ammonium ion removal capacity of MMZ increases with increase in initial ammonium ion concentration. The Langmuir and Freundlich adsorption isotherms were used to determine the adsorption characteristics. Ammonium-laden MMZ seems to be regenerated completely by sodium chloride solution at pH 11-12.
