The catalytic influence of methionine on the electroreduction of Bi(III) ions in chlorates (VII) solutions with varied water activity

► The methionine influence the rate of Bi(III) electroreduction in chlorate (VII) ► The activity water influence the rate of Bi(III) electroreduction in chlorate (VII). ► This fact is connected with the active complex formation on electrode surface. ► The complex formation on the electrode is connected with methionine adsorption.
