| Abstract: | The COD values of potassium hydrogen phthalate standard solutions were measured respectively in the same condition by potassium dichromate method and oxidation micro-reflux method. The experimental results showed that oxidation micro-reflux method had the advantages of convenient operation and high accuracy. There was no significant difference between these two methods. |
