MATHEMATICAL SIMULATION OF THE FORMATION OF A MERCURY-ELECTRODE SURFACE

A general approach to the mathematical simulation of the formation of a mercury drop at the surface of a disk electrode was suggested. The m ain parameters of prepared hanging-drop mercury electrodes (radius, ma ss, and volume of a drop) can be calculated fi-om the time of mercury deposition from solution that contains Hg-2(2+) and measured under gal vanostatic and potentiostatic conditions. A good agreement between the ory and experimental data was illustrated by the example of forming st ationary drop mercury ultramicroelectrodes.
