摘要

To well describe the photoassisted-electrochemical process for treatment of the contaminated water, a new kinetic model was established based on the intrinsic reactions of the process. The kinetic model correlated apparent kinetic constants to operational parameters including applied current, initial dye concentration and flow rate. Degradation experiments were carried out with boron-doped diamond (BDD) anode and carbon nanotubes-polytetrafluoroethylene (CNTs-PTFE) cathode. The proposed kinetic model was validated by the experiments of CI. Acid Blue 92 degradation in aqueous solution. The goodness of fitting (R~2 = 0.96) demonstrated that the new model could describe both the kinetics and the hydrodynamics of the photo-electrochemical system.
