【Abstract】 The electrooxidation of plant hormone indole 3 acetic acid(IAA) has been researched on. The results show that the eletrooxidation of IAA on GC is diffusion controlled and irreversible. The diffusion coefficient of IAA in phosphate buffer has been determined by different methods and charge transfer coefficient β and charge transfer rate constant ( k 0 ) are also illustrated. The mechanism involving one electron and one proton and the reason of inhibition of electrode is described.更多还原
