Abstract: In this paper,the aminating electroreduction of pyruvic acid was studied by potentiodynamic method.We have discussed a variety of factors of this reaction, such as style of cells,material of electrodes,temperature,the concentration of pyruvic acid and the buffer,oxygen resolved in the solution,etc.,which infuence the curve of linear sweep. The possible mechanism of the aminating electroreduction of pyruvis acid was obtained and we consider it as a CE reaction.

Key words: electrochemical reduction, pyruvic acid, alanine, potentiodynamic method, electrochemical reduction, pyruvic acid, alanine
