An ITO electrode slab optical waveguide spectroelectrochemical measurement system was built for simultaneous Visible attenuated total reflection (ATR) and electrochemical measure-ments and was applied to study the spectroelectrochemical behavior of iodine at the ITO electrode. The cyclic voltamogram and the potential-absorbance curve at 430nm for the redox reaction of iodine were observed and the formation of iodine was confirmed by the Visible ATR spectra of iodine (λ_<max>=430nm) which showed blue-shift compared with those of gasous iodine as well as iodine in non-polar solvents (λ_<max>=500〜600nm). Moreover, the linear responses of the peak current and the maximum absorbance for the oxidation reaction of iodide were obtained to the concentration of iodide in aqueous samples.
