Anodic Stripping Voltammetry (ASV) was introduced within a decade of Flame Atomic Absorption and played a major role in lowering limits of detection. Originally it was performed with a hanging mercury drop electrode which, of course, has numerous health risks. It was updated by creating in situ mercury film electrodes, of which the data shown here is legacy, as is the experiment. Other stripping surfaces have come into play, one of which is the bismuth-coated carbon or gold electrode (pdf). The nice data my students at Kenya Methodist University got was exceptionally good on a gold electrode.
In this data there is substantial noise so students will continue their data handling journey. As always the LOD is the goal of the journey as well as understanding selectivity
