| Abstract: | In this study,dichromate method and heating method of saving energy and rapid method are adopted to determinate the chemical oxygen demand in dealing with various kinds of wasted water.The study has suggested accuracy and preciseness of the three measurements all meet the demands.Heating method of saving energy and rapid method are more energy-saving and environmental friendly. |
| Keywords: | dichromate method heating method of saving energy rapid method chemical oxygen demand |
