Abstract

Background and Objective: Single anode contact glow discharge electrolysis (s-CGDE) is one of plasma electrolysis technology which is commonly used for waste water degradation. The aim of this research is to increase the effectiveness of waste water degradation by using multi anode CGDE (m-CGDE). Methodology: Synthetic Linear Alkylbenzene Sulfonate (LAS) waste was used with the initial concentration of 100 ppm in 0.02 M KOH electrolyte solution, the operating temperature was maintained in 30-60°C, using 1.6 mm diameter of tungsten anode and 5 mm diameter of SS-304 cathode. Results: The tests conducted were measurement of LAS concentration using Methylene Blue Active Substance (MBAS) method and measurement of H2O2 concentration as an indicator of OH radicals production using iodometric titration. Conclusion: Variable processes that produced the largest percentage of LAS waste degradation up to 99.97% were 700 V, 500 rpm stirring speed and 3 anodes (m-CGDE) with total energy 1264.2 kJ mmol-1 of LAS.
