摘要
由于C l-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C1-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C l-干扰消除方法进行了评述。
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.
