【摘要】 本研究介绍了用硫酸锰代替硫酸银作催化剂快速开管测定废水中COD的方法。该方法降低了分析成本 ,且使样品的回流时间缩短到 12min ,而准确度和精密度同标准法基本相同。此法取样量少 ,消解速率快 ,适用于大批量水样的测定。

【Abstract】 The determination of COD Cr in wastewaters by using quickly opening tube method and MnSO 4 as a catalyst instead of Ag 2SO 4 is introduced.The method can reduce analytical cost and shorten analytical time to 12 min,its accuracy and delicacy are the same as the standard method.The method needs a small quantity of sample and has a rapid analytical speed.It is suitable for determination of a great quantity of samples.
