| 摘 要： | 化学需氧量（chemicaloxygendemand，简称COD）是表征水体受有机物污染程度的一项重要指标。实验采用微波消解分光光度法测定废水的COD。对影响测定废水中COD的因素进行了研究，并确定了相关的实验条件。实验结果表明，与传统重铬酸钾法相比，本方法快速，简单，结果可靠。 |

| Abstract: | The chemical oxygen demand （COD） is referred as an important indicator of polluted organic substance in water. In the experiment we adopt the microwave digestion speetrophotometric method. The effective factor of determination COD in wastewater has been analysised. The experimental condition of this method are determined. Compared to the traditional potassium chromate method, the experimental results show that this method is simple, rapid and reliable. |
