| Abstract: | It is reported that COD is determined rapidly with the catalyzer of manganese sulfate in the mixture of sulfuric acid and phosphoric acid. Through experiments,the best determining conditions of this method are 0.2 g MnSO4,20 mL H2SO4-H3PO4,(H2SO4∶H3PO4 = 5∶1)and circumfluence time 15 min. |
