There were many advantages of determination of chemical oxygen demand（COD） by rapid method,such as rapid,low cost,and so on.It was important to improve its accuracy.Based on HJ/T399-2007,a laboratorial study on determination of COD in low-concentration standard solution by rapid method was carried out.The result was that there were many important factors affected the determination,such as calibration curve,digestion tubes,environmental temperature,preassembled mixed reagents,and so on.
