✦ Synopsis

The nitrate ion oxidation at platinum electrodes from AgNO, in acetonitrile soIutions has been studied under a wide range of experimental conditions. LiCIOL O-4 M was used as supporting electrolyte. Coulommetry, steady state polarization curves in unstirred solutions, rotating disk electrode and chronopotentiometry were employed as electrochemical techniques to analyse the electrode reaction. During the electrolysis AgZ+ ions were detected. Ags+ is obtained through a nitrate catalytic reaction pathway according to: NO; + M = M(NOs) +6e-M(N0,) + Ag+ = NOsAg+.
