Abstract
A reverse flow injection spectrophotometric method for determination chlorine dioxide was developed with leucomethylene blue as the coloration reagent. By this method low concentrations of chlorine dioxide in water were determined in the presence of Cl2 and anion species such as OCl−, ClO2 − and ClO3 −. The linear range of ClO2 measurement is 0–1.91 mg/L with a detection limit of 0.02 mg/L. The presence of chlorine and hypochlorite ion can be masked by using oxalic acid. Chlorate does not interfere with the measurement. The permissible maximum concentration of ClO2 − is 3.0 mg/L.
