2. Potential Sweep Methods

Potential sweep methods are those utilizing an applied potential that changes with time as the excitation signal. The most common waveform is that of a linear sweep, beginning at a potential far removed from the E0’ for the species of interest and increasing in magnitude at a constant rate. The current passing at the working electrode is measured as a function of the applied potential, with electron transfer accomplished by scanning the potential through the regions on either side of the E0’. The most common potential sweep methods are linear sweep voltammetry (LSV), cyclic voltammetry (CV), and anodic stripping voltammetry (ASV).
