摘要
将标准重铬酸钾法加以改进后用于测定糖蜜酒精废液这一典型高氯废水的化学需氧量,对标准水样研究测定结果表明,该方法具有较高的精密度和准确度、较强的抗氯离子干扰能力,实测水样的加标回收率在95%～103%之间。
This paper demonstrates the determination of Chemical Oxygen Demand in molasses alcohol waste water with the modified standard K2Cr2O7 method. Molassess alcohol waste water is the typical type in high CI. The determination results of standard water sample indicate that the accuracy and veracity of the method are good, the capacity of resisting the affect of CI is high and the recovery rates of actual water sample added standard material between 95%- 103%.
