Abstract

This study elucidates the COD removal of dye (Rhodamine B) through electrochemical reaction. Effects of current density (7.2 to 43.3 $mA/cm^2$), electrolyte type (NaCl, KCl, $Na_2SO_4$, HCl), electrolyte concentration (0.5 to 2.0 g/L), air flow rate (0 to 4 L/min) and pH (3 to 11) on the COD removal of Rhodamine B were investigated. The observed results showed that the increase of pH decrease the COD removal efficiency. Whereas, the increase of current density;NaCl concentration and air flow rate caused the increase of the COD removal of Rhodamine B.
