Abstract

Multi-Contact Glow Discharge Electrolysis (m-CGDE) technique have successfully degraded linear alkylbenzene sulfonate (LAS) surfactant with high efficiency. The degradation process was conducted in 0.02 M electrolyte solution NaOH with electrical voltage at 800 V and anode at 10 mm depth. The anode number and addition of Fe2+ ion greatly influenced the efficiency of the degradation. In the experiment using number of anode of 4, the percentage of LAS degradation achieved approximately 99.46% in 90 min, with energy consumption of 721.06 kJ/mmol. The addition of Fe2+ ions will increase the LAS degradation, by using 40 mg/L of Fe2+ ions in the reactor, LAS was degraded approximately 97.95% and 807.82 kJ/mol energy consumed during the operation.
