| 摘 要： | 氯离子浓度高于５００ｍｇ／Ｌ时，对ＣＯＤｃｒ的测定呈混浊干扰，通过加入ＨｇＳＯ４络合氯离子，可消除氯离子含量达２０００ｍｇ／Ｌ的干扰，过量的ＨｇＳＯ４对ＣＯＤｃｒ结果无影响。

| Abstract: | When Cl - is higher than 500mg/L Determination of COD cr appears turbid By adding HgSO 4 complexing Cl - The interference may be cleared when Cl - amounts to 2000mg/L Too much HgSO 4 has no effect on the result of COD cr |
