摘要
由于氯离子在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氯离子进行处理。本文从方法的原理、消除效果及适用范围等方面对目前国内在COD测试中主要采用的氯干扰消除方法进行了分析对比。
Chloride ion in determining COD will interference the measurement results,especially in the water sample for high chlorine and low COD, the interference is particularly serious,COD determination process of chlo ride ions in the water samples for processing. From the principle of the method to eliminate the effect and applica- ble range currently used mainly in the COD test chlorine interference cancellation method to analysis and compari- son.
