    Abstract
  • Accurate, timely and environmentally friendly detection of water Chemical oxygen demand has become an important research topic in the field of environmental monitoring. A visible-light-responsive BiVO4/rGO film electrode was prepared by solution combustion method and rotating coating method for the determination of COD. The structure of the composite electrode was investigated by X-ray diffraction (XRD), surface area analysis(BET) and scanning electron microscope analysis(SEM). The results showed that the substrate was completely covered by BiVO4/rGO. The photoelectric properties were tested by cyclic voltammetry(CV), photocurrent-time (I-t) method, and the best performance was obtained when the calcination temperature was 500℃, the doped rGO was 5 mL, and the coating thickness was 4 layers. The results showed that stable and reliable test results could be obtained in the condition of a working voltage of 1.0 V, supporting electrolyte of 0.1 mol/L Na2SO4, illumination intensity of 400 μW/cm2 and pH of 6~8. The determination range of COD by BiVO4/rGO film electrode was 12.18~719.8 mg/L, and there was a good linear relationship between the transfer net charge (Qnet) and the theoretical COD value. When it was applied to the determination of COD in real water samples, the steady photocurrent could be reached within 60 seconds. The results were in good agreement with the national standard method, and the relative deviation was less than 5%. Therefore, BiVO4/rGO coated electrode has the advantages of fast response, wide linear range and convenient operation, which can replace the traditional COD determination instrument.
