✦ Synopsis
The surface of a silver wire of a fibrous texture, pretreated by storing in Hg(Ag) is converted into a fine crystalline solid amalgam in the form of a passive skin layer. Applied as the base surface for film electrode, but containing some amount of silver, this layer replaces very well the pure mercury as an electroactive liquid layer.The apparatus for cyclic renovation of the film thickness from 50 nm to 70 nm is described. The promising analytical parameters such as the reproducibility and low residual current are presented.
