Abstract

Linear Alkylbenzene Sulfonate (LAS) is an organic compound which is commonly found in the detergent waste. Contact Glow Discharge Electrolysis (CGDE) is a plasma electrochemical technology that produces hydroxyl radical (•OH) in large quantities and can be used for LAS degradation. This study has been conducted to investigate the influence of Fe2 + ion concentration in LAS degradation using Contact Glow Discharge Electrolysis. The results show that Fe2 + ions can suppress •OH recombination into H2O2 and increase LAS degradation with the greatest LAS degradation at a rate of 99.28% during 60 minutes using Fe2 + ion concentration of 20 mg/L. COD value has decreased 34.5% after CGDE process using one anode with Fe2 + ion of 20 mg/L during 120 minutes.
