%X Electrochemical reduction is one of the most suitable methods for the treatment of highly nitrate-contaminated solutions. This work focuses on the optimization of parameters influencing the electrochemical denitrification of water by the Ti/RuO<sub>2</sub> + IrO<sub>2</sub> electrode. The methodological approach used consists in carrying out a series of electrolysis by scrutinizing the reaction selectivity according to the experimental conditions. For this study, the&nbsp;<img src=\"Edit_bad0325e-d09d-400a-9284-3d11e4af6e04.png\" width=\"30\" height=\"15\" alt=\"\" />&nbsp;ions concentrations before and after electrolysis were determined by UV-vis absorption spectroscopy. The results of the process optimization showed that the electrochemical reduction of<img src=\"Edit_495b55d8-e0d7-457d-9b7b-6f8c30f635e2.png\" width=\"30\" height=\"15\" alt=\"\" />is efficient at neutral pH after 120 mn of electrolysis at -100 mA. In contrast to works found in the literature, this study highlighted the process modeling that could open interesting perspectives to develop new treatment methods of polluted waters.
