An ITO electrode slab optical waveguide spectroelectrochemical measurement system was built for simultaneous Visible attenuated total reflection (ATR) and electrochemical measurements and was applied to study the spectroelectrochemical behavior of iodine at the ITO electrode. The cyclic voltamogram and the potential-absorbance curve at 430 nm for the redox reaction of iodine were observed and the formation of iodine was confirmed by the Visible ATR spectra of iodine (λ_max = 430 nm) which showed blue-shift compared with those of gasous iodine as well as iodine in non-polar solvents (λ_max = 500 ∼ 600 nm). 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.
