Cyclic Voltammetry (CV) is a simple, but powerful, technique for the s
tudy of electrochemical processes. The use of CV is discussed from a p
ractical viewpoint, using examples of reversible reactions, adsorption
of a gas on a metal, metal deposition and formation of a polymerised
film These examples have been chosen to highlight the type of informat
ion which can be obtained from these current vs. electrode potential c
urves.
