Berladyn I. Temporal and spatial self-organization in electrochemical systems.

The object of research: the processes, which occur in electrochemical system in the area far from thermodynamic equilibrium. The aim of research is ascertaining of value energy profit of electrolysing at the various conditions, when the spatial dissipative structures occur; the theoretical evaluation of possibility of the temporal dissipative structures occuring in the system, where gassing anode dissolution and cathode precipitation takes place; the studying of influence of ions of metal for the system stability of electropolishing of chrome. Methods: the linear theory of stability, bifurcation analysis, voltammetry, and optical method. The mathematical models of anode dissolution and cathode precipitation of metals in the potentiostatic conditions with electrode gassing. The computer analysis of dependence of amplitude and frequency of current in the mathematical models was carried out. There was ascertained the value of area of the potentials of electropolishing of chrome, where sodium dissolved and the autooscillations of current occurs. The dependence of the energy profit of electroprecipitation of cooper from the spent solutions in galvanostatic conditions was ascertained at the various spatial dispositions of electrodes.
