“…It was found that under conditions of water shortage when treating with plasma-activated water, the germination of Vigna mungo L. seeds increased by 10–15% [ 40 ]. Andreev et al showed that plasma-activated water in laboratory conditions could improve the drought tolerance of seeds (10–20%) of radish [ 41 ], wheat [ 42 ], and other crops, as well as increase the rate of seed germination under drought conditions. A number of other laboratory examples are provided in the review article [ 43 ].…”

In this work, we, for the first time, manufactured a plasma-chemical reactor operating at a frequency of 0.11 MHz. The reactor allows for the activation of large volumes of liquids in a short time. The physicochemical properties of activated liquids (concentration of hydrogen peroxide, nitrate anions, redox potential, electrical conductivity, pH, concentration of dissolved gases) are characterized in detail. Antifungal activity of aqueous solutions activated by a glow discharge has been investigated. It was shown that aqueous solutions activated by a glow discharge significantly reduce the degree of presence of phytopathogens and their effect on the germination of such seeds. Seeds of cereals (sorghum and barley) and fruit (strawberries) crops were studied. The greatest positive effect was found in the treatment of sorghum seeds. Moreover, laboratory tests have shown a significant increase in sorghum drought tolerance. The effectiveness of the use of glow-discharge-activated aqueous solutions was shown during a field experiment, which was set up in the saline semi-desert of the Northern Caspian region. Thus, the technology developed by us makes it possible to carry out the activation of aqueous solutions on an industrial scale. Water activated by a glow discharge exhibits antifungicidal activity and significantly accelerates the development of the grain and fruit crops we studied. In the case of sorghum culture, glow-discharge-activated water significantly increases drought resistance.

The use of plasma‐activated water (PAW) treatment is a promising technology that has many advantages, such as high efficiency, flexibility, environmental safety, and no residue. Thus, PAW has been applied in the agriculture industry to increase agricultural production. The application of PAW technology in agricultural production should emphasize its systematic nature, controllability, and operability, making it practical. This review systematically illustrates the production of PAW and the factors influencing it. The application of PAW in agriculture and its mechanism are discussed, including the effect on seed germination, the promotion of plant growth, and the control of plant diseases and pests. The implications of PAW for agriculture production and some of the related challenges are discussed. This review provides a deeper understanding of the viability of PAW technology in agriculture production. © 2021 Society of Chemical Industry.

“…It is well known that the nitrites and nitrates are formed in air plasma treated solutions through the dissolution of nitrogen oxides formed in the air plasma by gas-phase reactions of N 2 and O 2 (Eq 1-7), along with the formation of NO 2and NO 3in the plasma treated water (Eq 8-11) [16,20,21,55]…”

“…The reactive species generated in the gas phase interact with solvated charged salts and water to induce numerous physico-chemical transformations including precipitation of solid salt crystals in seawater demonstrated in this work. Subsequently, ions produced from APP penetrate through the gas-liquid interface and subsequently produce secondary species reacting with the water [20,21]. Several studies have been conducted by discharging plasma on water surface to produce plasma activated water (PAW) [16,22].…”

Water connects every aspect of life. Only 4% of the world's water is fresh water, where most of water sources have different degrees of salinity. As a result, billions of people around the globe face water scarcity which is a global challenge. Desalination technologies which separate the fresh water from the solvated salts ions in saline water are attracting major attention. However, conventional desalination processes including thermally and pressure driven processes are highly energy intensive. To address this issue, here we report that the atmospheric-pressure plasma (APP) treatment of saline water can be a new potential alternative low-energy and green desalination route. Meanwhile, valuable salts are recovered by direct salt crystal precipitation within a short plasma processing time. During desalination and salt precipitation, plasma activated desalinated water (PADW) is generated and can be used for clean energy generation by water splitting and sustainable agriculture by enhanced plant seed germination. In turn, functional nanomaterials can be extracted from the precipitated salt. The PADW exhibited low salinity of 5.6 ms/cm with low pH value of 2.1. The unique intrinsic PADW chemistries further enhanced the electrochemical water splitting in both hydrogen evolution reaction (HER) at a Pt electrode and oxygen evolution reaction (OER) at a RuO 2 electrode compared with the conventional acidic solution of similar pH. Moreover, the feasibility of using PADW in sustainable agriculture was demonstrated by enhancing mungbean seed germination using tap water mixed with PADW. At optimum mix concentration, both seed germination rates and germination percentages increased. Finally, we demonstrated the feasibility of synthesis of high-value 2D nanomaterials exemplified by Mg(OH) 2 nanosheets via single step thermal process using the salt precipitated from the seawater by the plasma process. Combined with straightforward use of renewable electricity to generate APPs, this study reveals the plasma potential for sustainable recovery of clean water, clean energy generation, sustainable agriculture, and manufacturing of advanced functional nanomaterials -all from the greatest treasure of our blue planet -seawater.
