Linear Sweep Voltammetry

Learn how to use linear sweep and cyclic voltammetry to study electrolysis reactions with different electron transfer kinetics and transport properties. See examples of voltammograms for reversible, quasi-reversible and irreversible reactions and how they depend on scan rate and potential.

Linear sweep voltammetry. The following example shows one of the most common uses of sweep techniques. When a redox probe is immersed in a solution, the voltage sweep starts in a region of potential where few reactions of interest take place. It continues through the kinetically controlled region and into the diffusion-limited region.

Learn the basics of LSV, a technique to measure the current response of an electrode as a function of potential. See examples of LSV curves for reversible and irreversible redox couples, and how to calculate formal potentials and peak currents.

Learn about the method of voltammetry where the current at a working electrode is measured while the potential is swept linearly in time. Find out how to identify unknown species, determine concentration, and apply linear sweep voltammetry to irreversible reactions.

Learn how to use linear sweep voltammetry LSV to study the electrochemical response of materials. Find out how to calculate key parameters such as peak current, peak potential, and half-peak potential for reversible and irreversible systems.

Applications of Linear Sweep Voltammetry. As we learned in the previous section, the limiting current in linear sweep voltammetry is proportional to the concentration of the species undergoing oxidation or reduction at the electrode surface, which makes it a useful tool for a quantitative analysis.

Linear Sweep Voltammetry LSV is a basic potentiostatic sweep method. It is equivalent to a one-segment cyclic voltammetry experiment In LSV, working electrode potential is swept linearly between final and initial values and current is measured as a function of time. The most common output from an LSV experiment is current vs. potential

Polarography or linear sweep voltammetry LSV or cyclic voltammetry CV is the most common method of electroanalytical chemistry 1-3, pioneered by Heyrovsky and honored by a Nobel Prize in Chemistry in 1959. The classical Randles-Sevcik theory of polarograms is based on the assumption of diffusion limitation of the active species
