The objective of this work is to establish new amperometric and potentiometric methods for the determination of copper (II) in an aqueous medium. To achieve this goal, a device for measuring the current intensity and the potential difference as a function of the concentration of Cu (II) has been developed. The current intensity and the potential difference as a function of the concentration of Cu2+ ions were measured. Correlation curves were established. The influence of the distance between the two electrodes, of the pH and that of the conductivity on the intensity of the measured current or on the potential difference was determined. The results obtained show a good correlation on the one hand, between the intensity of the current and the [Cu2+] and on the other hand between the potential difference and the [Cu2+] in the aqueous medium. Analysis of the results indicate that: pH and conductivity have no influence on the linearity of the correlation curves. Better linearity is obtained with a distance of 2 cm between the two electrodes. This study shows the possibility of measuring copper (II) in an aqueous medium by simple amperometry or potentiometry using a probe.
