Title: linear-scan voltammetry
Long Title: IUPAC Gold Book - linear-scan voltammetry
DOI: 10.1351/goldbook.09141
Status: current

Definition
Voltammetry in which the electric current is recorded as the electrode potential is varied linearly with time. See figure.Linear scan voltammogram of current against applied potential for a reversible redox couple.


Notes
1) The peak current is expressed by the Randles–Ševčík equation.
2) The scan is usually started at a potential where no electrode reaction occurs.
3) LSV corresponds to the first half cycle of cyclic voltammetry.
