MOUNICH, K. et al. Study and Conception of a Potentiostat at Competitive Prices and its Application for Assessing Aluminum Corrosion Inhibition. Port. Electrochim. Acta [online]. 2024, vol.42, n.1, pp.71-91.  Epub 29-Fev-2024. ISSN 0872-1904.  https://doi.org/10.4152/pea.2024420105.

A potentiostat is a device that enables to measure I that flows through one of the electrodes, by imposing a E. It was invented in 1942, by Hickling. Potentiostats available on the market offer a wide variety of functions. Unfortunately, their prices are high, which is mainly due to a sophistication that is not necessary for experiments such as those practiced at the undergraduate level. Therefore, this paper proposes the fabrication of a multi-channel potentiostat that is inexpensive, interdisciplinary, and enables to plot, for several Ec cells, a certain number of curves describing the evolution of the measured electrical quantities. Specifically, it allows to measure Icorr and analyze the solution chemical reactivity.
