A laboratory scale batch process was conducted to investigate the feasibility of a hybrid system of zero-valent iron (Fe0) with three different adsorbents for the removal of nitrate (NO3-) and ammonium ions (NH4+) from aqueous solution. The maximum nitrate removal was observed for Fe0-sepiolite hybrid system at 45ºC for 24 h reaction time. The rate of NO3- removal increased with the increase in initial NO3- concentration. NH4+ ions produced during the denitrification process by Fe0 were successfully removed by the adsorbents, with the removal efficiency in the order of GAC > sepiolite > filtralite. Results of the present study suggest that the use of hybrid systems could be a promising innovative technology for achieving simultaneous removal of NO3- and NH4+ from aqueous solution.
