摘要
探讨了工业废水氯碱样中COD的2种测定方法,重铬酸钾法和20 min快速密闭催化消解法。实际情节况表明,20 min快速密闭催化消解法更适合黑龙江昊华化工公司的工业废水氯碱样中COD的测定。
The two methods of the determination of COD in chlor alkali industry waste water were investigated, including potassium dichromate method and 20 min fast airtight catalysis digestion method. The result show that 20 min fast airtight catalysis digestion method is more suitable for the determine of the chloralkali industry waste water.
