The electrochemical conversion of nitrate to nitrogen gas on tin (Sn) and lead (Pb) cathodes was systematically investigated in an electrolyte solution of 2 M NaCl and 0.05 M NaNO3, resembling brine wastes generated from ion exchange processes. The objective was to enhance the yield of nitrogen production while reducing residual nitrate concentrations in compliance with drinking water regulations. Employing varying cathodic potentials, the results demonstrated that the nitrogen yield significantly increased on the tin cathode, achieving 85% at a potential of -2.8 V. Notably, while the residual concentrations of nitrate and nitrite were within acceptable limits, the levels of ammonia exceeded the Maximum Contaminant Level, indicating the need for additional treatment. The increase in nitrate reduction rate with higher cathodic potentials was attributed to the formation of ion pairs, supporting the theory of cationic catalysis. This study provides insights into effective electrochemical strategies for dealing with nitrate pollutants in brine-produced wastes from ion exchange, promoting sustainable waste management solutions.
