Abstract:Linear sweep voltammetry(LSV) was employed to investigate the influence of the initial concentration of Cr6+, pH of solutions and the scanning speed of potential on the polarization curves of Fe electrode. The three optimum values were given from experimental data. Based on the relationship of peak potential, peak current density and scanning speed, it is found that the electrochemical process is irreversible.
Key words: linear sweep voltammetry; polarization curve; chromium residue solution
