| 摘 要： | 介绍了测定高浓度氯离子水样CODMn的一种新方法。本方法利用乙酸银去除氯离子的干扰，在一定的条件下，用高锰酸钾作为氧化剂和自身指标剂，用草酸钠还原过量的高锰酸钾，通过计算求出CODMn值，本文法适用范围更广。

| Abstract: | A new method is introduced to determine COD Mn in the water sample containing high concentration of Cl -.The silver acetate is used to dislodge disturbance of Cl -.At some conditions,permanganic acid kalium is used as oxidant and self-tracer agent,sodium oxalate is used to reduce excessive permanganic acid kalium,and then the value of COD Mn is caculated. |

| Keywords: | water sample containing high concentration of Cl - silver acetate permanganic acid kalium sodium oxalate COD Mn |
