Study and Conception of a Potentiostat at Competitive Prices and its Application for Assessing Aluminum Corrosion Inhibition

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.
