摘要
Cl-会严重干扰高氯废水COD的测定结果,在COD测定过程中必须消除Cl-的干扰。文章从测定原理、消除效果及适用范围等方面对国内COD测定中采用的Cl-干扰消除方法进行了比较,指出对不同Cl-浓度和COD的水样应分别采用相应的消除方法。
Since the chloride ions interferes with the measurement results of high chloride-containing wastewater, the influence of chloride ions must be eliminated during COD determination process. The methods for eliminating the influence of chloride ions were compared in terms of the determination principles, the elimination effects, the application scopes and so on, and it was thought that appropriate methods should be used for water samples having different chloride ion concentrations and COD.
