Treatment of Acid Blue 113 Dye Solution Using Iron Electrocoagulation
The electrocoagulation (EC) treatment of Acid Blue 113 (AB 113) was performed on the basis of chemical oxygen demand (COD) removal efficiency using an iron anode. The process variables, including current density (1–5 A/dm2), pH (5.5–7.5), and supporting electrolyte concentration (1–3 g/L) were investigated. Under the optimum operating conditions, more than 91% COD removal efficiency was found. The optimum conditions were obtained with 3 A/dm2 of current density, pH 6.5, and 2 g/L of supporting electrolyte concentration. COD removal rates obtained during the EC process can be described using a pseudo‐kinetic model. The experimental kinetic data fit well with pseudo first‐order kinetic model, with no significant change on the rate constant after 3 A/dm2 of current density. The absorption spectra and Fourier transform infra red analysis were also performed to characterize the mechanism and nature of dye cleavage.
