Production of Chlorine Dioxide Using Hydrogen Peroxide and Chlorates

Chlorine dioxide was produced by the reduction of chlorate with hydrogen peroxide in strongly acidic media. To avoid reaction interference during measuring procedures, UV spectra were acquired to monitor reduction. This led formation chlorine and notable concentrations chlorite hypochlorous acid/chlorine, suggesting that peroxide:chlorate ratio is important. Once chlorates are transformed dioxide, surplus promoted further chlorinated species down less-important species. Moreover, stripped outlet gas flow. A linear relationship established between amount limiting reagent consumed maximum height absorption peak at 360 nm after testing different ratios chlorate, allowing calculations formed. verify reproducibility method, a test four replicates conducted peroxide/chlorate solution where not due presence medium test. Results confirmed efficient this oxidant, 8.0 ± 0.33 mmol L?1 400–450 min conversion percentage 97.6%. Standard deviations 0.14–0.49 obtained oxidation (3.6–6.5% average), indicating good reproducibility.
