英文摘要 | A pair of new redox peaks of ascorbic acid at a platinum electrode was found and studies in detailed by spectroelectrochemistry and electrochemistry technologies. this is a quasi-reversible redox reaction with a one-electron transfer process. The intermediate of tertiary carbon free radical exists in this process. The appearance reaction rate constant and the diffusion coefficient were investigated. A possible reactiion mechanism has been proposed. |
