摘要：Electrochemical techniques have been generating great interest due to their wide range of applications and their ease of use. For this reason, in recent years’ electrochemical techniques such as cyclic voltammetry, anodic voltametric stripping, chronoamperometry and linear voltammetry have been developed. Linear voltammetry is one of the most widely used electrochemical techniques, where a voltage range is applied to a solution with the analyte and then current data is collected as a response. For this, an electrochemical cell with its 3 electrodes (working electrode, counter electrode, reference electrode) and a device for voltage control and current evaluation (potentiostat) is used. A potentiostat is an electronic device that allows the voltage or current to be regulated according to the electrochemical technique to be performed. The devices are usually very expensive due to their high precision, for this reason, our project is focused on the development of a low cost system that allows us to recognize redox systems by using linear voltammetry. our potentiostat system was able to differentiate in a redox salt (sodium chloride) from the support electrolytes (chlorohydric acid, nitric acid, sulfuric acid), allowing us to evaluate redox behavior at a cost of less than $ 40.
