Oxidation of Aqueous Paracetamol by Pulsed Corona Discharge

Paracetamol degradation in aqueous solution by non-thermal plasma

“…Panorel et al [7] obtained an energy yield between 14 and 18 g/kWh, which is a little higher than our results.…”

“…AOPs involve several techniques such as TiO 2 catalysis, Fenton's reaction and non-thermal plasmas (NTP) [5,6]. AOPs with NTP have already been applied to the treatment of pharmaceutical compounds in aqueous media [6,7] and showed a high potential. In this study, a NTP created by a dielectric barrier discharge (DBD) was used as an AOP for the degradation of paracetamol in liquid.…”

Elucidation of the degradation pathways of sulfonamide antibiotics in a dielectric barrier discharge plasma system

“…[28,29,39], and it has been well known that inorganic ions such as NO 3 À , NH 4 + and SO 4 2À are generated by cleavages of bonds containing N and S atoms during the oxidation treatment [19,40,41]. The toxicity of degradation byproducts may be a matter of concern.…”

“…They found that among various reactive species ozone played a major role in the degradation of antibiotics. Pulsed corona discharge plasma as a means for advanced oxidation has also been applied to the oxidation of aqueous pharmaceuticals [28,29]. The authors reported that this method is effective in the oxidation of pharmaceuticals and ultimate oxidation byproducts are low-molecular carboxylic acids.…”

Degradation of pharmaceutical compounds in water by non-thermal plasma treatment

“…On the contrary, for ibuprofen no significant improvement is observed in oxygen atmosphere. Very good energy yields are reported especially for the degradation of indomethacin, reaching 172 g/kWh (133.5 Â 10À9 mol/J) under optimized conditions (acidic pH, oxygen) (Panorel et al, 2013a). These high values recommend this corona discharge reactor similar to an electrostatic precipitator, with the liquid introduced as droplets or jets through the plasma zone and short high voltage pulses (100 ns, 20 kV), as one of the most efficient ones reported up to now.…”
