TLDR
In this paper, a study of the electrooxidation of ammonia as a possible new method of ammonia removal during waste-water treatment was undertaken. But the most favorable potentials were determined using a conventional three electrode electrolytic cell.Abstract:
A study was undertaken of the electro-oxidation of ammonia as a possible new method of ammonia removal during waste-water treatment. Reaction rates were measured in the concentration range of 1.2×10−4 M to 1×10−2 M ammonia and at pH values of 5–13. The influence of the polarization rate (0.05–0.5 V min−1) and the ammonia concentrations on the oxidation peak current were studied. A number of electrocatalysts were evaluated and most favourable potentials were determined using a conventional three electrode electrolytic cell.read more

The anodic oxidation of ammonia at platinum black electrodes in aqueous koh electrolyte
H. G. Oswin,Mark Salomon +1 more
TL;DR: In this article, the anodic oxidation of ammonia in aqueous potassium hydroxide solutions at platinum black electrodes was studied and a kinetic scheme of consecutive reactions was proposed. But the authors did not consider the effect of the anisotropic nature of the solution.

Kinetics of electrochemical oxidation of ammonia in alkaline solution
TL;DR: In this article, the kinetics of the anodic oxidation of ammonia in alkaline solutions at platinized platinum has been investigated by the galvanostatic method and it is suggested that the rest potential is a reversible hydrogen potential determined, by the atomic hydrogen produced by the chemical decomposition of ammonia at the electrode.
