The kinetics of oxidant formation in water and aqueous solution of Mohr's salt under the action of radiation from a hot plasma of a spark discharge and products formed in the discharge itself has been investigated. The oxidizing agents are nitrous acid, radicals HO₂∙/HO₂^•−, and a long-lived complex that decompose into peroxynitrite and peroxynitrous acid. Nitrous acid is identified directly by its absorption spectrum. The detector of all active species is ferrous iron in the Mohr's salt solution, which is oxidized to ferric. It has been shown that radiation plays the main role in the formation of oxidants, which creates active species in distilled water at a depth of 3–4 cm. In a solution of Mohr's salt, radiation acts to a depth of no more than 1 cm. Radiation does not carry active species; it creates active species throughout the entire thickness of the liquid that it penetrates. In contrast, cold plasma, itself, carries active species and transfers them to the sample through the gas–liquid interface. Products formed in the water under the action of radiation and water solutes absorb radiation. As a result, after processing the distilled water, the depth of the radiation effect decreases. The mechanism of active species formation under the action of radiation is based on the direct absorption of radiation by the parent molecules, bypassing the stage of ionization. Due to this, the yield of oxidants under the action of hot plasma pulsed radiation turns out to be more appreciable than under the action of cold plasma and reaches ~ 10 (100 eV)⁻¹. Plasma radiation may be a more advantageous technology for producing activated water.

已经研究了在火花放电的热等离子体辐射和放电本身形成的产物的作用下，在水和莫尔盐水溶液中氧化剂形成的动力学。氧化剂是亚硝酸、自由基 HO ₂ ∙/HO ₂ ^•−，以及分解成过亚硝酸盐和过亚硝酸的长寿命复合物。亚硝酸可通过其吸收光谱直接识别。所有活性物质的检测器都是莫尔盐溶液中的亚铁，它被氧化成三价铁。已经表明，辐射在氧化剂的形成中起主要作用，氧化剂在蒸馏水中 3-4 厘米的深度产生活性物质。在莫尔盐溶液中，辐射作用的深度不超过 1 厘米。辐射不携带活性物质；它在其渗透的整个液体厚度中产生活性物质。相比之下，冷等离子体本身携带活性物质并通过气液界面将它们转移到样品中。在辐射和水溶质的作用下在水中形成的产物吸收辐射。结果，在处理蒸馏水之后，辐射效应的深度减小。在辐射作用下形成活性物质的机制是基于母体分子直接吸收辐射，绕过电离阶段。因此，在热等离子体脉冲辐射作用下的氧化剂产率比在冷等离子体作用下更可观，达到~10（100 eV）^-1。等离子辐射可能是一种更有利的生产活化水的技术。
