Quick Summary

potential ramps
potential ramps Figure 3: The potential ramps applied to the indicator electrode during selected forms of polarography and the corresponding polarograms. E is the potential; I, the current; δI, the current difference; IAC, the AC current; t, the mercury electrode drop time; and m, the points at which measurements are made.

AC voltammetry is an electroanalytical technique used in chemical analysis. It involves applying a DC potential ramp with an added alternating potential to an indicator electrode immersed in a solution containing the analyte. The method specifically measures only the AC portion of the resulting current as a function of the DC potential. This technique is particularly useful for studying reversible electrochemical reactions because it requires the reaction to occur in both forward and reverse directions. Voltammetry in general can be used for both qualitative and quantitative analysis of various substances by monitoring the current as the potential is varied.12
