用MnSO4作催化剂开管测定废水COD
RAPID DETERMINATION OF CODCr IN WASTEWATER BY USING MnSO4 AS CATALYST
【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.
