摘要（英）：

The invention, which belongs to the technical field of chemical detection, discloses an electrochemical control COD rapid detection device and method. The method comprises the following steps: S1, sequentially adding a buffer solution, potassium ferricyanide, hydrogen peroxide, luminol and a standard COD solution with a certain concentration into a detection pool; S2, applying a pulse voltage to aworking electrode and recording a light-emitting value; S3, cleaning the detection pool, repeating the step S1, changing the concentration of a standard COD solution, and repeating the S2; S4, repeating the S3, and drawing a relationship standard curve of a COD value and a luminescence value; S5, cleaning the detection pool, sequentially adding a buffer solution, potassium ferricyanide, hydrogenperoxide, luminol and the sample, repeating the S2, and recording the luminescence value of the sample, and S6, acquiring the COD value of the sample by referring to a standard curve. The electrochemical control COD rapid detection device and method have advantages of high detection stability and accuracy, great convenience in operation, simplicity in cleaning, low reagent consumption, low cost and good secondary pollution prevention effect.
