| Abstract: | Potassium dichromate is a high accuracy method for evaluating chemical oxygen demand,but it needs large space,consumes large amount of the reagents,time and electricity and water.While,rapid determination,which can save time,water,power,reagents,as well as human power,is a simple handle method.Through comparative test,the feasibility of rapid determination was proved.The precision and accuracy of this low cost method can achieve the international requirements.This method is particularly suitable to monitoring and evaluating the process control of wastewater treatment. |
