| 摘 要： | Cl-的存在会对COD的测定造成较大的干扰。该文以高浓度ABS废水作为分析水样,对AgNO3沉淀、HgSO4络合和标准曲线校准3种消除Cl-干扰的方法进行了研究。AgNO3沉淀法和标准曲线校准法都可以消除Cl-的干扰,但是各存在一定的缺陷。HgSO4络合法是简单易行的COD测定方法,适于推广。

| Abstract: | The existence of Cl-will make big disturbance to the determination of COD.We used three methods to eliminate the disturbance of Cl-: sedimentation by AgNO3,reaction with HgSO4 and standard curve for calibration.Sedimentation by AgNO3 and standard curve can eliminate the disturbance successfully,but they are both limited in use.Method of reaction of HgSO4 and Cl-is easy to operate,and easy to be used extensively. |
