Paper Title:
A Novel Electrode for the Degradation of Methylene Blue in Electrochemical System: Preparation and Characterization
  Abstract

Organic wastewater pollution control was one of the focus researches for environmental workers. In this study, high active electrode was made and hydrogen peroxide production via cathodic reduction of oxygen was studied, the H2O2 generated in the optimization of research and the effect of dye wastewater degradation under the typical conditions were explored. The effects of mass ratio between graphite and PTFE, Na2SO4 concentration, cathodic potential, pH and gas flow rate on hydrogen peroxide output were investigated. The optimized operational parameters were as follows: graphite and PTFE 5:1, pH=6, Na2SO4 concentration 0.5 mol/L, oxygen flow rate 450mL/min, and cathodic potential -1.2 V (vs SCE). Hydrogen peroxide concentration could reach 66.17 mg/L after 2h at optimized condition. Meanwhile, dye removal could reach about 70% at the same time. Therefore, the use of active electrode as cathode has shown promising prospect in dye wastewater treatment.
