Abstract
|
|
|
This study elucidates the COD removal of dye (Rhodamine B) through electrochemical reaction. Effects of current
density (7.2 to 43.3 mA/cm2), electrolyte type (NaCl, KCl, Na2SO4, 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.
