en عمومى General مقاله اصیل Original Article <div style="text-align: justify;">Background: Sulfur dioxide (SO2) is an air pollutant that can cause a wide range of health effects. Its&rsquo; removal can be achieved in one way through oxidation using non-thermal plasma (NTP) technology. This study aimed to optimize the dielectric barrier discharge (DBD) Plasma Reactor Parameters to maximize the SO2 removal efficiency using the Taguchi Method.<br> Methods: At first, the operational condition of the DBD plasma reactor was investigated and optimized using a factorial design. Then, the effective parameters on SO2 removal from air using the selected reactor were optimized using the Taguchi method.<br> Results: According to the results, the DBD reactor packed with inert ceramic granules (ICGs) was selected as the optimal reactor condition, and analysis of the experiments using the Taguchi method indicated that packing the reactor with ICGs has the most contribution in the SO2 removal from air. The maximum removal efficiency of the optimized reactor was achieved as 100% at the optimum condition of SO2 concentration of 600 ppm, flow rate of 2 lpm, and voltage of 25 kV. Also, the result of the validation test showed that the results of the experiments and the model were in good agreement.<br> Conclusion: In this study, following the Taguchi method, the effects of parameters influencing the SO2 removal using a plasma reactor were analyzed. According to the results, it was concluded that the ICGs can be a good choice for packing the DBD reactor for maximizing the SO2 removal efficiency, which was increased by 100% at the optimum condition.</div> Sulfur dioxide, Air pollutants, Research design, Oxidation-reduction, Analysis of variance 1 8 http://ehemj.com/browse.php?a_code=A-10-1-415&slc_lang=en&sid=1 Niloofar Damyar damyar@semums.ac.ir 100319475328460021524 100319475328460021524 No Research Center for Public Health Sciences and Technologies, Semnan University of Medical Sciences, Semnan, Iran Fariba Mansouri fmmansouri@gmail.com 100319475328460021525 100319475328460021525 No Department of Public Health, Shahid Sadoughi University of Medical Sciences and Health Services, Yazd, Iran Ahmad Khademi ah.kh360@gmail.com 100319475328460021526 100319475328460021526 No Laser and Plasma Research Institute, Shahid Beheshti University, Evin 1983963113, Tehran, Iran Ali Khavanin Khavanin@modares.ac.ir 100319475328460021527 100319475328460021527 Yes Corresponding author: Department of Occupational Health, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iran Ahmad Jonidi Jafari ahmad_jonidi@yahoo.com 100319475328460021528 100319475328460021528 No Department of Environmental Health Engineering, School of Public Health, Iran University of Medical Sciences, Tehran, Iran Hassan Asilian asilia_h@modares.ac.ir 100319475328460021529 100319475328460021529 No Department of Occupational Health, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iran Ramazan Mirzaei rammir277@gmail.com 100319475328460021530 100319475328460021530 No Department of Occupational Health and Safety Engineering, Social Determinant of Health Research Center, School of Health, Mashhad University of Medical Sciences, Mashhad, Iran
