Contact Glow Discharge Electrolysis (CGDE) is one of the plasma electrolysis technologies for producing hydroxyl radicals that can be used for the process of waste degradation. This study has been conducted to establish the influence of voltage, electrolyte concentration, and anode depth in the Linear Alkylbenzene Sulfonate (LAS) degradation process using CGDE and its energy consumption. The results indicated that the greatest LAS degradation at a rate of 96.19% was achieved with an energy consumption of 2692 kJ/mmol, that was obtained using 600 V, at a Na 2 SO 4 concentration of 0.03 M, and anode depth of 20 mm during 30 minutes of the process. Meanwhile, the lowest energy consumption was 1802 kJ/mmol with the LAS degradation at the rate of 82.11% that was obtained when using 600 V, at a Na 2 SO 4 concentration of 0.03 M and anode depth of 0.5 mm during 30 minutes of the process. These results showed that CGDE is an effective method to degrade LAS. © 2016 American Institute of Chemical Engineers Environ Prog, 35: 962–968, 2016
