Sažetak

The work focuses on the mechanism of the electroreduction of indium ions in an aqueous electrolyte containing hydrochloric acid. The potential region for the electroreduction of indium ions on platinum (-0.3 to -1.5 V), nickel (-0.8 to -1.5 V), and Pt/In (-0.63 to -1.5 V) electrodes was determined by recording potentiodynamic polarization curves. The influence of several factors, including temperature, indium ion concentration, scan rate, and disk electrode rotation speed, on the electroreduction of indium was investigated. It was established that increasing both the temperature and the indium ion concentration in the electrolyte accelerates the reduction process. The process is primarily controlled by the diffusion of indium ions to the cathode surface. Furthermore, polarization curves were obtained using a rotating platinum disk electrode. The dependence of the current density on the electrode rotation speed at different potentials showed that the electroreduction process of indium ions in an aqueous electrolyte is accompanied by diffusion polarization.
