摘要
研究了用硫酸锰代替硫酸银作催化剂快速测定废水COD的一种方法———开管法,经实验研究得最佳测定条件为:消解温度165℃,消解时间12min,反应体系的酸度10.8 mol/L,硫酸锰用量10 g/L。
Quick determination of COD in wastewater using opening tube method and MnSO4 as catalyst instead of Ag2SO4 is described. The optimum determining conditions are as follows： decomposition temperature 165℃, decomposition time 12 min, acidity 10.8 mol/L, MnSO4 dosage 10 g/L. It is easy, fast, accurate and sensitive, high merit with the standard method compared This method can reduce analytical cost by using MnSO4 as catalyst instead of Ag2SO4. Many water samples can be dissociated with the method and it fits for the determination of bulky water samples.
