“…The •OH radical can be formed in numerous processes, which occur when the high-energy electrons or other reactive species strike neutral molecules such as O 2 , H 2 O and N 2 present in the air and O 3 generated by plasma [10,[12][13][14]38]:…”

“…The latter has been recently developed and has become a very promising technique for the removal of organics from water due to its high efficiency, low energy and operational requirements and ecofriendly nature [5,6]. Several types of plasma discharge have been used for water treatment, such as dielectric barrier discharge (DBD) [6][7][8][9], plasma jet [2,10], gliding arc discharge (GAD) [11][12][13] and atmospheric pressure corona discharge. Corona type plasma is created in a strong nonuniform electric field, on the tips and in the direct vicinity of the corona-carrying electrode, which is usually a system of multiple needles or wires with a small radius of curvature.…”

“…While this phenomenon has been largely examined and used to develop a variety of catalysts for photodegradation processes [18,19], research into plasma-catalyzed organic degradation in water remains limited. The literature data report the use of BiPO 4 in decolorization of crystal violet [20], g-C 3 N 4 /TiO 2 catalysts for decolorization of Acid Orange 7 [21], Mn-doped cobalt oxyhydroxide catalyst in decolorization of caffeic acid [9] and Bi 0.5 Fe 0.5 VO 4 /honeycomb ceramic plate in decolorization of doxycycline hyclate [7] by DBD plasma, tin containing aluminophosphate molecular sieves in decolorization of Acid Green 25 [13], TiO 2 in decolorization of textile wastewaters [12] and laterite soil in decolorization of Orange G [11] by GAD plasma, and Cu-TiO 2 in decolorization of Reactive Red-198 by an atmospheric pressure Ar plasma jet [10]. However, there is limited documentation of the use of catalysts in corona plasma degradation.…”

Monoclinic Bi2O3 was applied for the first time, to the best of our knowledge, as a catalyst in a process of the dye degradation by the non-thermal atmospheric pressure positive pulsating corona discharge. The research focused on the interaction of the plasma-generated species and the catalyst, as well as its role in the degradation process. Plasma decomposition of the anthraquinone reactive dye Reactive Blue 19 (RB 19) was performed by the self- made reactor system. Bi2O3 was prepared by electrodeposition followed by thermal treatment, and characterized by XRD, SEM and EDX techniques. It was observed that the catalyst promoted decomposition of plasma-generated H2O2 into •OH radicals, the principle dye-degrading reagent, which further attacked the dye molecules. The catalyst improved the decolorization rate by 2.5 times, the energy yield by 93.4%, and the total organic carbon TOC removal by 7.1%, respectively. The excitation of the catalyst mostly occurred through the strikes of plasma-generated reactive ion and radical species from the air, accelerated by the electric field, as well as by the fast electrons with the energy of up to 15 eV, generated by the streamers reaching the liquid surface. Those strikes transferred the energy to the catalyst and created the electrons and holes which further reacted with H2O2 and water, producing the •OH radicals. This was indentified as the primary role of the catalyst in this process. Decolorization reactions followed the pseudo first order kinetics. Production of H2O2 and dye degradation rate increased with the increase of input voltage. The optimal catalyst dose was 500 mg dm-3. Decolorization rate was little lower in the river water compared to the one in deionized water due to the side reactions of •OH radicals with the organic matter and inorganic ions dissolved in the river water.

“…Simultaneously, a significant amount of OH (X) (at 3200-3600 cm −1 ) is detected. During the discharge, water vapor molecules dissociate to produce •OH, leading to a gradual increase in OH(X) [37][38][39][40][41]. As the discharge continues, the water vapor will have significant impact on the FTIR measurement after 180 s.…”

Inhibit ammonia volatilization from agriculture and livestock by air plasma-activated water

Ammonia volatilization in agriculture and livestock is a considerable cause of air pollution and a significant way of N loss. In this study, we propose a method of using air plasma-activated water (PAW) to inhibit ammonia volatilization from agriculture and livestock and report the inhibitory effect under different discharge times and concentration gradients. PAW was generated through needle–water discharge, while ammonia waters with different concentrations served as simplified models for ammonia release. The compositions of the gas/liquid products of the PAW and those after mixing with ammonia water were detected and analyzed. It was found that the PAW could effectively inhibit the NH3 volatilization from ammonia water over a large range of conditions, however, NH3 volatilization promotion could also happen in some cases. The inhibition rate (IR) generally increased with the longer discharge time of the PAW and decreased with the higher ammonia water concentration. As the discharge time increased, the PAW became more acidic and had more active N components, converting more volatile NH3 to NH4 + when mixed with ammonia water. Finally, a relationship model was developed between the IR and pH of the mixture. The IR basically decreased with the increase of the mixture pH, and reached ∼100% when a PAW with a discharge time of 7.5 min or 10 min was mixed with ammonia water with a mass fraction of 0.15%, or PAW of 10 min mixed with 0.25% ammonia water in this study, with the mixture pH lower than 8. The basic chemical process and possible reaction mechanisms were discussed. The proposed method not only effectively reduces ammonia volatilization but also adds more N elements in the form of NO3 − and NH4 +, which further improves fertility.

“…Active species that play a role in degrading compounds in liquid waste include hydroxyl radicals (•OH) and hydrogen peroxide (H2O2). Nevertheless, waste degradation efficiency is influenced by several factors, including the reactor system, voltage, electrodes, solution pH, temperature, input gas, and conductivity (Anggraini et al, 2018;Chanan et al, 2018;Kusumandari et al, 2022;Kusumandari et al, 2022;Rasyidah et al, 2018;Wulandari et al, 2019).…”

This study employed the corona plasma method combined with TiO2-N/PS photocatalyst to degrade dye pollutants. The plasma reactor consisted of two needle-shaped stainless steel electrodes connected to a voltage of 8 kV. Methylene blue (MB) solution was used as a model pollutant with varied initial concentrations of 10, 50, and 100 ppm. The degradation efficiency was evaluated based on the absorbance of the degraded MB solution measured using a UV-Vis spectrophotometer. The results exhibited that the longer plasma treatment duration caused the absorbance value of the degraded MB to decrease, and then the MB degradation efficiency increased. MB-10 demonstrated a maximum degradation efficiency of 99.40% after plasma treatment for 30 minutes. Meanwhile, MB-50 and MB-100 reached maximum degradation efficiencies of 95.29 and 86.55% efficiency after plasma treatment for 60 minutes. The greater initial MB concentration caused the longer degradation process. Furthermore, the results revealed no increase in degradation efficiency due to the addition of TiO2-N/PS photocatalyst into the plasma treatment. The degradation efficiencies of MB-10, MB-50, and MB-100 under TiO2-N/PS-combined plasma treatment for 30 min were 94.48, 81.57, and 5.22%, respectively. This suggests the possibility that the UV light generated during the plasma process cannot activate the TiO2-N/PS photocatalyst.
