Cyclic voltammetry measurement
Linear Sweep Voltammetry (LSV) is a measurement of response current at the potential scan on sample from initial to final potentials at a certain scan rate.
Cyclic voltammetry (CV) is a reversible LSV measurement which scan potential turned to reverse direction after reaching final potential and scan back to initial potential. In CV, reversibility of the products produced in forward scanning can be analyzed during backward scanning. Because of this characteristic CV has been applied widely. If a CV conduct with potential wave form as described below then we can study the substance characteristic as:
- Stability of oxidized and reduced forms.
- Molecular adsorption in redox process.
- Measurements of kinetic rate constants.
- Study of reaction mechanism.
- Reversibility of electrochemical reaction.
- Standard redox potential, Eo=(Epa+Epc)/2
- Electron transfer number, DE=Epa-Epc= 58/n, n: electron transfer number per mole
