抄録

UV/vis spectrophotometry/channel flow electrode was developed in order to determine the dissolution rate of metallic ions from the corroded metal electrode. In the present method, the relation between absorbance A_s and the flux of dissolved ions ψ is expressed by the following equation: A_s = εκψV_m^-2/3, where ε is molar absorptivity, κ a constant, and V_m the mean electrolyte flow rate. The present method was applied to the simultaneous determination of Fe(II) and Fe(III) dissolved from Fe during the active dissolution and the pitting initiation.
