Abstract

The effluent produced by the electroplating industry contains hazardous and toxic chemicals
that pose a threat to living organisms and ecosystems. Consequently, it is essential to employ
advanced treatment technologies to remove the toxicants from the wastewater. Over the past
two decades, the concept of Electro Fenton has been developed and demonstrated as an
effective method for significantly alleviating pollutants in wastewater, making it a promising
solution for treating wastewater. In the present investigation, the efficiency of the Electro
Fenton (EF) process in removing Chemical oxygen demand (COD) from electroplating
wastewater using stainless steel as the sacrificial electrode was examined. The influence
of various operating parameters, including pH, hydrogen peroxide concentration, reaction
time, and Fe2+ concentration, was investigated with the help of Box-Behnken design (BDD)
in Response surface methodology (RSM). Notably, EF treatability studies demonstrated that
optimal conditions of pH 2, Fe2+ concentration of 0.005M, H2O2 concentration of 0.5M, and
RPM of 450 resulted in more than 75% COD removal. Hence, the sacrificial electrodes can
be effective in removing COD from the wastewater.
