Aluminosilicate-catalyzed electrochemical removal of ammonium cation from water -kinetics and selectivity.

Aluminosilicate-catalyzed electrochemical decomposition of ammonium cation (NH) in water was investigated using NH-saturated clinoptilolite and copper-nickel electrodes in the presence of different salts and acidic species. The results showed beneficial roles of chloride anion and moderately acidic media. NH adsorbed by the zeolites was converted with a 98% selectivity into nitrogen.
