The maximum adsorption peak of ClO2 is at 360 nm,which could be used as the basis for quantitative de-termination of ClO2. Interference factors,wavelength selection,measuring range and accuracy of spectrophotometric determination of chlorine dioxide in drinking water have been studied by experiments. Results indicate that this method can rapidly and accurately determine ClO2 in drinking water with low concentrations. The average recovery rate of low concentration ClO2 in water is more than 91.4%,and the average recovery rate of ClO2 with medium or high concentration in water is between 89.8%-91.1%.
