Kinetics and mechanism of the electrochemical oxidation of nitrite ion dissolved as sodium nitrite in dimethylsulphoxide solutions on platinum electrodes

The kinetics of the electrochemical oxidation of NO<sup>2</sup>− ion dissolved in DMSO has been studied on Pt electrodes at temperature ranging from 25 to 44°C, by means of potentiostatic E/I curves and by relaxation techniques. The oxidation reaction is explained in terms of a consecuti...

Sumario:The kinetics of the electrochemical oxidation of NO<sup>2</sup>− ion dissolved in DMSO has been studied on Pt electrodes at temperature ranging from 25 to 44°C, by means of potentiostatic E/I curves and by relaxation techniques. The oxidation reaction is explained in terms of a consecutive reaction scheme which involves, as rate-determining step, nitrite-ion discharge on an adsorbed intermediate at the reaction interface, the latter apparently obeying a Langmuir isotherm.
