Abstract :

The adsorption studies on the removal of ammonium ions from aqueous solution of ammonium chloride using non treated natural zeolite and treated fly ash zeolite1 as a new adsorbent, both are locally available and cost effective was carried out under varying experimental conditions. The maximum adsorption was observed to be a function of solution of pH, contact time and initial concentration of solution has been found out that specific surface of natural zeolite as well as fly ash zeolite1 takes leading part at the adsorption of ammonium ions from aqueous sloutions at room temperature with different concentrations. Natural zeolite showed maximum adsorptive removal of ammonium ions at about pH 3 and doses 1 gm per 50 ml solution in 2.5 hours while the fly ash zeolite1 showed maximum adsorptive removal of ammonium ions at pH 3, doses 0.2 mg per 50 ml aqueous solution in 60 minutes. Ion exchange is probably one of the major adsorptive mechanisms for binding of NH4+ ions on the surface of natural zeolite as well as fly ash zeolite1. This hypothesis is strongly supported by experimental analysis. On the basis of experimental results it can be said that the adsorbent natural zeolite and fly ash zeolite1 may be used in developing an adsorptive technology for the removal of ammonium ions.
