The research investigated the efficiency of the electro-Fenton process in removing reactive yellow dyes, with the highest removal efficiencies occurring under specific conditions. The results of the kinetic study showed that the data in this research follow the pseudo-first-order kinetic model.
Electro-Fenton is one of the advanced oxidation processes, which have been applied effectively to degrade recalcitrant organics such as dyes in aqueous solutions. In the present research, the efficiency of electro-Fenton process in the removal of reactive yellow dyes of 15 and 42 were investigated. In this regard, the effects of various parameters such as pH, H2O2 concentration, current density, contact time and initial concentration of dyes were investigated. Colorimetry along with spectrophotometry was used to measure the concentration of the residual dye. The highest removal efficiencies (95%) for both reactive yellow dyes of 42 and 15 occurred at pH = 3, H2O2 concentration = 5 mg/L, contact time = 20 min, current density = 0.3 A and initial concentration = 80 mg/L. Also, the results of the kinetic study showed that data in this research follow the pseudo-first-order kinetic model.
