245 0 0 a| Rapid prediction of hydrogen peroxide concentration eletrogenerated with boron doped diamond electrodes
520 1 _ a| The electrochemical generation of hydrogen peroxide with boron doped diamond electrodes was experimentally investigated to assess the influence of basic operating parameters on H2O2 production rate. Experiments were conducted in an undivided electrolytic cell, at room temperature, and different operating conditions of air bubbling, stirring and current density. Current density was the most influencing parameter affecting H2O2 generation. Therefore, an equation was proposed to describe hydrogen peroxide generation at BDD electrodes as a function of current density and electrolysis time. Experimental data showed that H2O2 concentration significantly increased during the first 45 min of electrolysis, and thereafter it remained constant until the end of the reaction. The equation was able to describe well this H2O2 production pattern. Additional experiments were conducted to validate the proposed equation. Good agreement between theoretical predictions and experimental data, as assessed by the Chi square goodness of fit test, was observed.
