测定中氯离子的干扰及消除方法探讨作者：陈辉来源：《北方环境》2011年第12渗透印章
期 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-双极化高频头进行处理。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- usb周边干扰消除方法进行了评述。 关键词： COD； 氯离子； 干扰； 消除方法

stract： Due to the Cl- ion in the detection of COD interferes with the measurement results, especially for high chlorine low COD samples, the interference is very severe, therefore COD determination process need to water samples in Cl- processing. The article from the principle, eliminate the effect and applicable range of the current domestic during COD test using Cl interference eliminating method were reviewed in this paper.
