Abstract
Abstract The electrochemical oxidation of 2,4,6-tribromoaniline in aqueous sulphuric acid solutions, at different concentrations, and in aqueous 60% perchloric acid solution, at a platinum electrode, has been studied by rotating disc electrode and cyclic voltammetry. An irreversible first oxidation process, controlled by diffusion is observed, in perchloric acid and in sulphuric acid concentration 9.0 M and perchloric acid solutions, is observed. Generally, this second process is kinetically controlled. The rate-determining step of both processes is attributed to the initial charge transfer for the electrode reaction under diffusion control or to an adsorption process, depending on the medium used.
