Abstract:

The method of COD_Cr rapid determination has been studied. The result of the long-term tests shows that both the accuracy and nicety of this method can meet the requirements of actual production and engineering debugging. It is suitable for daily analysis in labs and the rapid determination of engineering debugging on site.

Key words: chemical oxygen demand, potassium dichromate determination method, wastewater
