Ammonium Ion Removal from Wastewater by a Natural Resin

H. Moazed

A natural resin, Clinoptilolite, in the powder form was used in this study to remove ammonium ions from synthetic wastewaters. The concentrations of the ammonium ion (NH4+) in the synthetic wastewaters were 5, 10, 20, 30 and 40 mg L-1. Based on the batch kinetic experiments, the equilibrium time was determined to be one hour for synthetic wastewaters of 5, 10, 20 and 30 mg L-1 and 2 h for 40 mg L-1 ammonium ion concentrations. Batch adsorption studies were conducted using 40 mg L-1 ammonium ion solution and 1, 3, 5, 7 and 10 mg Clinoptilolite per 100 mL wastewater at room temperature. The experiments were conducted up to equilibrium time. The removal efficiencies obtained ranged from 68 to 92%, depending on the mass of Clinoptilolite used. Batch adsorption studies also indicated that the most applicable model for the sorption of ammonium ions from the synthetic wastewater with 40 mg L-1 ammonium ion concentration was the Freundlich isotherm model. Results of the study showed that powdered Clinoptilolite could be used in the removal of ammonium ions from synthetic wastewaters with high removal efficiency.
