摘要
介绍了用 Mn SO4代替 Ag2 SO4作催化剂测定废水中 COD的方法。该方法可降低分析成本 ,且使回流时间缩短为 30 m in,方法的变异系数、回收率分别为 0 .6 5 %和 96 .8%～10 0 .8%
MnSO 4 is used as a catalyst instead of Ag 2SO 4 for determination of COD in wastewater.The method can reduce analytical cost and shorten analytical time to 30 min.The variation coefficient and recovery efficiency of the method are 0.65% and 96.8%~100.8% respectively.
