A VOLTAMMETRY INVESTIGATION OF THE EXCHANGE PROCESSES RUNNING ON THE INTERPHASE CdSb/ELECTROLYTE

摘要

Processes running on the interphase between the non-doped p-conductive CdSb monocrystal and a liquid medium at various pH were investigated voltammetrically and simulated through thermodynamic calculations. The boundaries between electrode passivity and activity regions were determined for different pH of the solution, types, and intensity of electrode polarization. Atom absorption spectroscopy and polarographic measurements were employed to investigate the rate and the dynamics of crystal surface dissolution and measure the contents and the qualitative composition of the components produced during this process. All the data obtained were used to compose a scheme of the chemical reactions running at different surface states of CdSb and for various pH values.
