| 摘 要： | 由于Cl^-离子在COD测定中会干扰测量结果，尤其对于高氯低COD的水样，其干扰尤为严重，因此COD测定过程中需要对水样中的Cl^-进行处理。文章从方法的原理、消除效果及适用范围等方面对目前国内在COD测试中采用的Cl^-干扰消除方法进行了评述。

| Abstract: | Cl-ion interfers the determination of COD,which is more serious in the water samples of low COD with high Cl-concentrations.Therefore,it is necessary to have the Cl-in the water sample treated during testing.In this paper,the methods for eliminating the interfererce of Cl-in COD testing currently used in China are evaluated in the respects of the method principle,elimination results as well as the scope of application,etc. |
