“…The addition of t-butanol, which is a scavenger of •OH-radicals, resulted in the decrease in the phenol decomposition degree May, 2016 [1]. At the same time, the addition of alcohols (ethanol and 2-propanol) in the optimal amount (up to 0.1 mol/l) increased the hydrogen peroxide concentrations in glow discharge over water [27]. The ratio between the rates of these reactions will define the behavior of H 2 O 2 concentration.…”

We studied phenol decomposition in aqueous solution under the action of DC discharge at atmospheric pressure in air. The decomposition efficiency was 0.017 molecules per 100 eV. When the kinetics of forming destruction products was studied in detail, the peculiarities of air plasma action were revealed for the first time. Plasma action not only results in the formation of oxygen-containing products, which are usually formed under oxygen plasma action (hydroxyhenols, carboxylic acids, aldehydes), but also the formation of nitro phenols. The treatment is accompanied by hydrogen peroxide formation, a pH decrease, and nitric and nitrous acids formation. We also discussed the possible mechanism of the processes and the role of some active species in chemical transformations after determining some parameters of the discharge.

“…Liu et al [10] used a glow-like discharge plasma device to treat a sodium lactate solution, and the yield of hydrogen peroxide in activated sodium lactate is eight times higher than that of the PAW, reaching 325 μmol/L. Kuz'micheva et al [11] found that the yield of H 2 O 2 increased from 5:2 � 10 −4 mol=L to 1:4 � 10 −3 mol=L when glow discharge plasma was used to treat 0.01 mol/L Na 2 SO 4 and 0.1 mol/L ethanol mixed solution compared with only 0.01 mol/L Na 2 SO 4 . In our previous study [12], a DC-driven air plasma device has been used to treat solution containing H+, NO − 2 and NO − 3 species and achieved a better decontamination effect than PAW.…”

Ethanol solution as a disinfectant has been widely used in various fields. However, it has a significant bactericidal capability only when the volume fraction of ethanol is around 70%–75%. For such high concentration of ethanol solution, it has an irritating smell. When it is used for applications such as wound disinfection, it causes a stinging sensation. Low concentrations of ethanol solution are less irritating, but it is also less effective at killing bacteria. In this study, an idea for producing a green, efficient and less irritating disinfectant is proposed. It is based on a plasma‐activated low‐concentration ethanol solution (PAES). It is found that the plasma‐activated 10% volume fraction of ethanol solution can kill more than seven orders of magnitude of Escherichia coli, while the untreated 10% volume fraction of ethanol solution has no bactericidal effect. Besides, the PAES's activity remains unchanged after being stored at for three days. Further investigation shows that new compositions including peracetic acid, peroxynitrite, hydrogen peroxide and acetic acid are detected in the PAES, which together are playing the main role of the excellent and prolonged bactericidal effect.
