Adsorptive Voltammetry Behavior of an Antitumor Herbal Drug Idinonine |

Abstract: | The electrochemical behavior of idinonine (IDN) on the hanging mercury electrode has been investigated. In acetic acid buffer solution(pH=7.8), an adsorption-driven reduction peak of idinonine is obtained with the peak potential at -1.150V(vs.SCE), the electrode process involves single electron transfer reaction with α=0.834 and K_S=2.26 s~-1. The mechanism of the reaction is discussed simply. |
