Chlorite Ion Interference in the Spectrophotometric Measurement of Chlorine Dioxide

KÖrtvÉlyesi, Zsolt / Gordon, Gilbert

The presence of the Cl₂O₄⁻ complex, which forms in chlorine dioxide (ClO₂) solutions in the presence of chlorite ion, can result in significant error in the spectrophotometric measurement of ClO₂. In this article, the significance of the Cl₂O₄⁻ complex is demonstrated and the formation constant (K_eq) and the molar absorptivity of this complex are reported. Based on the K_eq and the molar absorptivity values, two methods are proposed to correct for the presence of the complex. By using the equation suggested in this article, the error of the determined ClO₂ concentrations is reduced to the level of errors associated with the spectrophotometric measurements.
