摘要
探讨了用XJ-Ⅰ型COD消解装置快速处理水样,KMnO4滴定测定化学需氧量的新方法。对常规消解和密封消解的两种测试方法进行了比较,实验结果表明,密封法消解应用于环境污水的分析,具有试剂用量少,加热速度快,准确度高等优点。
In this paper, a new method for COD determination with KMnO4 seal digestion is introduced. The comparison of experimental results by using two methods of seal digestion and standard method shows that the new method has some advantages such as small quantity of reagent used, quick heating and high accuracy.
