Cathodic voltage scan, application

Cathodic stripping voltammetry (CSV) may be considered the reverse of ASV in that the electrolytic deposition step is carried out at a positive (anodic) applied potential, the deposited analate then being stripped by application of a cathodic voltage scan. CSV has been used for the determination of various anions ... 

For electrochemical work it is important to know the limiting potentials that may be applied in oxidative, anodic, or reductive, cathodic, scans of solutions in which solutes can undergo redox reactions without the solvent being oxidized or reduced. These limits constitute the electrochemical window for the solvent. However, the breadth of this window, in terms of the applicable voltages, depends not only on the solvent itself, but also on the material of the working electrode involved, the reference electrode against which the potentials are measured, and the nature of the supporting electrolyte present.
