Mechanism of Ampicillin Degradation by Non-Thermal Plasma Treatment with FE-DBD

Abstract: This research focused on determining the effectiveness of non-thermal atmospheric pressure plasma as an alternative to advanced oxidation processes (AOP) for antibiotic removal in solution. For this study, 20 mM (6.988 g/L) solutions of ampicillin were treated with a floating electrode dielectric barrier discharge (FE-DBD) plasma for varying treatment times. The treated solutions were analyzed primarily using mass spectrometry (MS) and nuclear magnetic resonance spectroscopy (NMR). The preliminary product form… Show more

“…Degradation pathways were analyzed by many authors using various tools such as liquid or gas chromatography coupled to mass spectrometry (LC-MS, GC-MS) and nuclear magnetic resonance spectroscopy (NMR) enabling identification of typically several transformations products [45,134,142]. Generally, such studies show similar degradation patterns obtained with plasma treatment in comparison to the other oxidative water treatment processes.…”

“…In the study of Smith et al [134], plasma was generated in ambient air over the liquid surface by using a nanosecond pulsed DBD source with a floating electrode for the treatment of high concentrations of antibiotic ampicillin. The degradation rate was higher with increase in plasma treatment time.…”

“…Smith et al . determined also the potency of non-thermal atmospheric pressure plasma as an alternative to advanced oxidation processes for antibiotic removal from water 28 . The antibiotic, ampicillin, was completely eliminated during five minutes after air-plasma treatment giving ampicillin sulfoxide as the main product.…”

“…[1][2][3][4][5][6][7] Recently, our group determined the chemically active species present in wavariety of analytical methods and proposed the chemicals responsible for antibacterial properties of this solution. 8,9 One of the key challenges that remains is the generation of plasma-treated water in large volume for the real-world applications. One of the methods for water processing is the treatment of water by using reverse-vortex gliding arc the treated water.…”
