Linear sweep voltammetry is a voltammetric method where the current at a working electrode is measured while the potential between the working electrode and a reference electrode is swept linearly in time. Oxidation or reduction of species is registered as a peak or trough in the current signal at the potential at which the species begins to be oxidized or reduced. WebCV vs LSV • The key advantage of CV over simple LSV results from the reverse scan. • Reversing the scan after the electrochemical generation of a species is a direct and …
