| 摘 要： | 本文介绍了一种重铬酸钾法测定含氯废水COD的改进分析方法——氯耗氧曲线校正法，测定中不加隐蔽剂HgSO4，通过调整催化剂Ag2SO4的加入时间，测得表现COD值，再扣除Cl^-对COD的贡献值，得出实际COD值。与标准方法相比，本法的准确度高、精密性好，同时还可避免汞盐污染环境。

| Abstract: | An improved method,i.e.chloride oxygen demand calibration,for COD determination in high chloride water was presented in this paper.It needs only to adjust the catalyst's adding step and use no masking reagent,COD is the difference(between) total and chloride's contribution.Compared with the standard method,this has better accuracy and precision,and avoids the Environmental contamination by mercury. |
