The periodic current oscillations of Fe/HNO3 are presented in this paper. The effects of HNO3 concentration and imposed potential were investigated. The dropping method was used to change the local pH of the Fe/electrolyte interface, creating environments that favor the occurrence of current oscillations. Some interesting results were obtained and an explanation of the current oscillations is suggested.

Periodic Current

The periodic current oscillations of an iron electrode in p-toluenesulfonic acid (PTSA) solutions were investigated by cyclic volatammetry and potentiostatic polarization. The Fe/PTSA system is a new electrochemical oscillator and shows some interesting phenomena. The oscillations are ascribed to the alternate buildup and breakdown of Fe(OH)2 and Fe3O4 films.

Periodic Current

This paper presents current oscillations of a Zn anode in solutions of nitric acid and potassium dichromate. The effects of the nitric acid concentration were investigated. The system was analyzed using cyclic voltammetry, current-time plots and attractors. It was found that the concentration of nitric acid has a major effect on the behavior of the system and it is proposed that zinc hydroxide precipitation-dissolution processes are responsible for the current oscillations.
