| 摘 要： | 对经典测定水样ＣＯＤＣｒ的方法进行了改进，以硫酸银－硫酸铜作催化剂代替单独作用硫酸银，用适量硝酸银、硝酸铋代替硫酸汞消除氯离子的干扰，适当提高了消解用硫酸浓度，缩短回流时间。

| Abstract: | A new method determining COD\-\{Cr\} in water sample was introduced.Ag\-2SO\-4-CuSO\-4 as catalyst substituted for only Ag\-2SO\-2. To eliminate the interfenence of Cl\++,just the right amount of Silver nitrate,Bismuth nitrate replaced original Mercury sulfate,which enhanced conceatration of Sulphuric acid and shortened recirculation time. |
