| 摘 要： | 将样品中的颗粒物分离出来后，向样品中加入适量硝酸银，除去生成的氯化银沉淀，再将预先分离的颗粒物合并到水样中，混匀后测定。经过这样处理，既去除了水样中的Ｃｌ－，又保留了水样中原来的组份，保证了ＣＯＤ测定结果的准确性。

| Abstract: | For correctly determining concentration of COD, chemists separate particles from water sample, then they add Silver Nitrate into the sample to sedimentate chlorine. After that, they return particles into the sample and the influence of chlorine can be removed by the method. |
