What is Anodic stripping voltammetry?

Definition 15.21 University Chemistry — Year 3 · Chapter 15 — Electrode Kinetics and Electroanalysis

Anodic stripping voltammetry preconcentrates a metal by reducing its ions onto an electrode for a fixed time at a fixed potential, then scans the potential anodically and measures the current peak of its re-oxidation, which is proportional to the concentration in the solution.

Anodic stripping of lead with three standard additions (data of ). Left: the stripping peaks grow with each addition. Right: the least-squares line of peak height against added concentration crosses the axis at minus the concentration of the sample.
