Abstract: The electrochemically driven and persulphate-mediated oxidation of indole-3 ethanol has been studied in phosphate buffers. The electrochemical oxidation is carried out at PGE and a well-defined peak is noticed. The studies reveal that no UV/ vis - absorbing intermediate is generated during electrooxidation of indole-3 -ethanol (I). On the other hand, oxidation by persulphate follows pseudo-first-order kinetics having first-order with respect to substrate. This reaction takes place with a second-order rate constant of (0.25 ± 0.01) dm3 mol-1 S-1 .The redox mechanisms of electrochemical as well as chemical oxidation have been suggested and in both the oxidations the major product of oxidation is found as hydroxy dimer (VII).
