摘　　要：COD催化快速法中对测定结果干扰最大的因素是水样中的氯离子浓度。通过对不同氯离子含量的水样进行对照分析 ,讨论其干扰问题 ,从而制定出理想的去除方法 。The main factor that affected the result in the rapid determination of COD Cr by catalysis method was the concentration of chloride in water.The paper analysed different samples with different concentrations of chlorides,discussed the interference and found a satisfactory solution.According to this analysis,the rapid determination of COD Cr by catalysis method could be used rapidly and accurately in pratical monitoring.
