Electrocatalytic Oxidation and Determination of Cysteine at Oxovanadium(IV) Salen Coated Electrodes

Figure 5

Linear sweep voltammograms recorded at GC/VO²⁺-S in 0.1 M KCl with different concentrations of cysteine (0.0, 0.1, 0.2, 0.5, 1.0, 2.0, and 3.0 mM (a to g, resp.)) at a potential scan rate of 20 mVs⁻¹.
