ABSTRACT

Cyclic voltammetry is an important and very frequently utilized electrochemical technique because it ožers a wealth of experimental information and insights into the kinetic and thermodynamic details of many chemical systems. It was œrst reported in 1938, and then described theoretically by Randles in 1948. Cyclic voltammetry measurement is accomplished with a two-or three-electrode arrangement, whereby the potential relative to some reference electrode is scanned at a working electrode while the resulting current ›owing through a counter electrode is monitored. Cyclic voltammetry is o§en the œrst experiment performed in an electroanalytical study. It is rarely used for quantitative determination, but it is ideally suited for a quick search of redox couples, for understanding reaction intermediates, and for obtaining stability in reaction products.
