| 摘 要： | 通过采用铬法与锰法测定佛山科学技术学院校园湖水COD值以及铬法与锰法分析条件、氧化率的相互比较．其结果表明：铬法精度高于锰法，铬法比锰法氧化完全，因此，采用铬法来作为控制有机污染物综合性指标比用锰法更为适宜，在测定清洁的地表水COD值时可用锰法，但对于受污染的地表水用铬法更适合。

| Abstract: | Through adopting Cr method and Mn method to monitor the COD in campus lake water in Foshan University and comparing each other in the condition of analysis and in the rate of oxidation,the result indicates:the accuracy of Cr method is higher than Mn method,the oxidation of Cr method is more complete than Mn method,therefore,adoption of Cr method in the control of organism pollutant synthesizing index is more suitable than using Mn method.In monitoring the COD in the clean Earth's surface water,we can use Mn method,but for the contaminative Earth's surface water,Cr method is more suitable. |

| Keywords: | Cr method Mn method Earth's surface water COD value the rate of oxidation |
