“…However, if the generated DBD was not in close proximity to the water surface, some of these species might decay before entering the water (Dojcinovic et al 2011). These reactive species produced in the gas phase would be further carried to the water by the gas agitation caused by the ion wind (Cagnoni et al 2013;Karakas et al 2008;Vatazhin et al 2012). Under the conditions of high voltage, ionization of the nearby air molecules was realized, which resulted in the generation of ionized air molecules having the same polarity.…”

Degradation of aqueous 3,4-dichloroaniline (3,4-DCA) was conducted in a novel dielectric barrier discharge (DBD) plasma reactor. The factors affecting the degradation efficiency of 3,4-DCA and the degradation mechanism of 3,4-DCA were investigated. The experimental results indicated that the degradation efficiency of 3,4-DCA increased with increasing input power intensity, and the degradation of 3,4-DCA by the novel DBD plasma reactor fitted pseudo-first-order kinetics. Higher degradation efficiency of 3,4-DCA was observed in acidic conditions. The degradation efficiency of 3,4-DCA, the removal rate of total organic carbon (TOC), and the detected Cl(-) increased dramatically with adding Fe(2+) or Fe(3+). Degradation of 3,4-DCA could be accelerated or inhibited in the presence of H2O2 depending on the dosage. Several degradation intermediates of 3,4-DCA such as 1,2-dichlorobenzene, 2-chloro-1,4-benzoquinone, 3,4-dichlorophenyl isocyanate, 2-chlorohydroquinone, 3,4-dichloronitrobenzene, and 3,4-dichlorophenol were identified by gas chromatography mass spectrometry (GC-MS) analysis. Based on the identification of aromatic intermediates, acetic acid, formic acid, oxalic acid, and Cl(-) released, a possible mineralization pathway of 3,4-DCA was proposed.

“…e gradual extending of inhibition zone from the center corresponds with the air ow induced by the discharge ion wind, which is a characteristic of point-to-point/wire/plane discharges. For more details about the plasma sources and their properties, see, for example, our previous works [40,41] dealing with point-to-point cometary discharge, demonstrative work about the ion source induced air ow [42], or the review of several common plasma sources [43] suitable for decontamination. e spatial distribution of inhibition e ect for C. sphaerospermum for several exposure times.…”

e inactivation e ect of the combination of nonthermal plasma and hydrogen peroxide aerosol for the microbial decontamination of inner surface of cylindrical container buckets is studied on one bacterial and seven lamentous micromycete species and on airborne-contaminated cups. While the decontamination by single nonthermal plasma or hydrogen peroxide is not observable after 120 s, the strong decontamination by their combination occurs after 30 s of exposure. Moreover, observed total elimination of airborne contamination of plastic cups predetermines this method as a suitable alternative to the currently used method based on the application of hydrogen peroxide.

Abstract. At present, most machine-building enterprises focus on the problem of saving energy resources. The proposed system of air regeneration in industrial premises will allow to keep the air in the room at a comfortable temperature without removing it to the atmosphere. The second problem solved by this system is the prevention of pollutants entering the atmosphere. At the same time, the efficiency of this system is not inferior to analogs, and many of them even surpass. Energy costs are reduced by at least 30% because there is no need to use the system of regeneration of working elements. However, the development of this system requires the solution of a number of problems. One of the main problems is the control of the motion of particles in the corona discharge region. A number of differently directed forces act on a particle of a finely dispersed substance, which actually form the equation of motion of this particle. However, when composing the equation of particle motion, it is necessary to take into account the space charge in the outer region of the corona. With a fairly complex geometry of the core, it is impossible to take into account the influence of a volumetric charge analytically, and, consequently, the use of computer modeling tools is required. Another factor that needs to be taken into account is the appearance of an aerodynamic force arising from such a poorly understood phenomenon as the "ion wind" that appears in the presence of a corona discharge. The solution of the described problem will allow to create a system of air regeneration in industrial premises, allowing recirculation of polluted air without diversion into the atmosphere, which will reduce the cost of energy.
