Formaldehyde removal from gas streams by means of NaNO2 dielectric barrier discharge plasma

Formaldehyde removal by potted plant–soil systems

“…Therefore, the mitigation of formaldehyde is a significant practice. Till date, a lot of physical, chemical and biological techniques are well established for the purification of formaldehyde-polluted air [5][6][7]. * Corresponding author.…”

Study on Decomposition of Indoor Air Contaminants by Pulsed Atmospheric Microplasma

“…Production of OH and H radicals was due to the electron impact dissociation of H 2 O vapors [6,17]: $\text{e}+{\text{H}}_2\text{O}\to \text{e}+\text{H}+\text{OH}$…”

“…One of them could be an atmospheric pressure non-thermal plasma. Its generation starts from 8 kV, thus bulky power supplies and reactor are necessary [3–6]. Microplasmas, which are a dielectric barrier discharge non-thermal plasma, are generated at about 1 kV between electrodes faced together with a discharge gap on the order of micrometers.…”

Experimental Evaluation of Indoor Formaldehyde Decomposition Performance of Atmospheric Plasma Reactor Utilizing Sensor Network

“…Various researchers have demonstrated the removal of acetaldehyde or formaldehyde using atmospheric pressure nonthermal plasma reactors [22][23][24][25]. International Journal of Distributed Sensor Networks Storch and Kushner [26] performed a theoretical investigation into the removal of formaldehyde from atmospheric pressure gas streams using a dielectric barrier discharge system with a discharge gap size of 2 mm and a supply voltage of 40 kV.…”

“…It has been suggested that the decomposition process commences with the formation of OH and H radicals as a result of the electron impact dissociation of H 2 O vapor [25,31]. The detailed reactions responsible for the formation of these radicals are summarized in the following.…”
