摘要
化学需氧量是水体中有机物含量的重要指标。重铬酸钾法是测定化学需氧量的常规方法。在这个实验里,我们采用了COD的快速测定方法,对这种方法的准确度、精密度进行了分析,并对重铬酸钾法与快速测定法进行了对比实验,以验证其相关性。
The chemical oxygen demand is referred as important indicator of organic substance in water. The potassium chromate method is one regular method to determine COD. In the experiment, we adopt COD rapidly determined method and its accuracy and precision are discussed, the comparison of potassium chromate method and rapid determination are developed to testify the correlation.
