Abstract

Background & Objectives: Electro-OZONATION process (EOP) has a good potential for the removal of persistent organic pollutants. This process is a combination of OZONATION process and electricity for producing hydroxyl radical and removal of pollutants. The purpose of this study was to evaluate the EOP for SDBS degradation in AQUEOUS MEDIA.Materials & Methods: In this experimental study, a semi-batch reactor with four graphite electrodes of 120 cm2 area was used. The effects of pH (3-11), the inlet of ozone (6-30 mM / s), current density (16-85 mA/cm2), the initial concentration of SDBS (0.02-0.3 mM/L) and radical scavenger dose (0.2 mM/L) were studied. SDBS concentration measured by spectrophotometer (DR5000) by instructions provided in the standard method book.Results: The results indicate the high efficiency of this process in the removal of SBDS and COD. In optimum conditions of pH=3, current 85 mA/cm2, ozone flow rate 30 mM/s and initial SDBS concentration 0.02 mM/L, more than 99% removal was observed in 50 min. By changing the parameters of the optimum conditions, the process performance was decreased. High efficiency of COD removal in this process was obtained in 80 min. Influence of TBA in solution was the efficiency decrease of process to 80%.Conclusion: Electro-OZONATION process as an advanced oxidation process can reduce organic pollution industry and can be considered as an environmentally friendly process.
