%X In an electrochemical reactor using Pt as anode, graphite as cathode and Na_ 2 SO_ 4 as supporting electrolyte, the in situ generation of H_ 2 O_ 2 electrochemically was investigated. According to the orthogonal test, the main influencing factors on the H_ 2 O_ 2 generation, including pH, current density, oxygen flow and concentration of supporting electrolyte, were quantified, and the optimal combination of these factors was proposed. Then, two methods including regression analysis and BP artificial neural net works, were employed to model the H_ 2 O_ 2 generation that including the influencing factors. Also the models were evaluated, and the results showed that the H_2O_2 concentration of the cathode region could be predicated under certain conditions by both of the mathematic models. Moreover, the prediction accuracy of BP artificial neural net works was higher than that of regression analysis, and the former was more feasible to apply in on-line control system.
