The experimental parameters of cathodic stripping chronopotentiometry of chloride at a silver-film electrode are investigated and optimized. The chloride preconcentration is achieved in the form of silver chloride by a controlled potential oxidation of the working electrode under vigorous stimng. Ca
## Abstract New, renewable copper (Hg(Cu)FE) and silver (Hg(Ag)FE) based amalgam film electrodes applied for the determination of elemental sulfur using differential pulse cathodic stripping voltammetry are presented. With surface areas adjustable from 1 to 12 mm^2^, both electrodes are characteriz
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 merc
