Аннотация:On the basis of a model put forward, experimental data on the electrochemical ionization of solid gallium in carbonate buffer media are analyzed. It is shown that the formation on the electrode of a matrix consisting of the hydrolysis products of gallium ions Ga(3+) is the initial anodic step. The charge transport in this matrix proceeds via an ejection mechanism. At pH > 10, this matrix transforms into a reaction layer, which supplies Ga(OH)(2)CO3- complexes (at higher pH-Ga(OH)(4)(-) anions) to the electrolyte.
