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 0.02Â M electrolyte solution NaOH with electrical voltage at 800Â V and anode at 10Â 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 90Â min, with energy consumption of 721.06Â kJ/mmol. The addition of Fe2+ ions will increase the LAS degradation, by using 40Â mg/L of Fe2+ ions in the reactor, LAS was degraded approximately 97.95% and 807.82Â kJ/mol energy consumed during the operation.
