Processes of discharge ionization of Indium at platinum electrode in sulfate solutions

Annotation

Electrochemical characteristics of deposition and dissolution of Indium in sulfate solutions using the method of cyclic voltam-metry are defined. The effect of the polarization of the interval and sweep speed capacity at the place in the system of electrochemical reactions is studied. It is established that the processes occurring in the discharge-ionization of indium sulfate solutions have a stage character. The study of the influence of the potential sweep rate on the electrochemical behavior of indium showed an increase in current peaks and the shift of the potentials for the cathode process to negative values, and for the anode – towards positive values. This shows the irreversible nature of the test electrode processes.
