摘要

The redox reaction of various concentrations (in 1:1 molar ratio) of the [Fe(CN)_6]~3-/[Fe(CN)_6]~4- redox couple in the neutral borate-buf- fered (pH=8.4) electrolyte solution is studied on the Fe_80B_20 elec- trode passivated under strongly defined conditions. Impedance meas- urements in the potentiostatic mode and quasisteady-state polari- zation measurements are used. The results of measurements clearly show the electron transfer reaction occurring as the rate determining reaction in both directions (cathodic and anodic) vs. R_rev of the redox couple.
