| Abstract: | The method of semi micro- heating oven to measure COD in wastewater and industrial wastewater was introduced, with characteristics of water, power, time and chemicals saving compared with traditional methods. Dosage of HgSO4 was small to reduce secondary pollution of mercury salt when Ag2SO4-MnSO4 used as catalyst. The method was fit for measuring large amount of water sample with precision and accuracy. |
| Keywords: | COD semi micro-heating oven Ag2SO4-MnSO4 catalyst |
