Structure and Physicochemical Properties of Water Treated under Methane with Low-Temperature Glow Plasma of Low Frequency

Abstract

Our former studies delivered a strong evidence that water indirectly treated with low-temperature, low-pressure glow plasma of low frequency (GP) changed its structure depending on the atmosphere in which such treatment was performed (air, ammonia, and nitrogen) and on the time of the treatment (0 to 120 min). In every case, water of different physicochemical characteristics and interesting biological functions was produced. Therefore, the relevant studies were extended to treating deionized water with GP under methane. The resulting samples were characterized by means of ultraviolet/visible (UV/VIS), Fourier transformation infrared-attenuated total reflectance (FTIR-ATR), electron spin resonance (ESR) and Raman spectroscopies, differential scanning calorimetry (DSC), thermogravimetry, pH, conductivity, and refractive index. The generated samples of water had entirely different physicochemical properties from those recorded for water treated with GP in the air and under both ammonia and nitrogen. The treatment of water with GP under methane did not produce clathrates hosting methane molecules. Thermogravimetry delivered an evidence that the treatment with GP increased the aqueous solubility of methane. That solubility non-linearly changed against the treatment time.

Reaction of Lavandula angustifolia Mill. to Water Treated with Low-Temperature, Low-Pressure Glow Plasma of Low Frequency

“…Water treated for the same time with LGPG under nitrogen as described by Chwastowski et al, [7] produced LPGPN. LPGPC [13], LPGPO [9] and LPGPM [12] were prepared following the procedures described in the indicated references. LPGP of 38 • C was generated at 5 × 10 −3 mbar, 800 V, 50 mA and 10 KHz frequency in a plasmothrone patented by Oszczęda et al [1,10].…”

“…Following the invention of LPGP and the construction of a generator suitable for the treatment of water [1,7,10], a series of papers were published on the specific physical and physicochemical properties of water treated with LPGP in the air (LPGPA) [8], under all oxygen-free nitrogen (LPGPN) [7], ammonia (LPGPAM) [11], methane (LPGPM) [12], carbon dioxide (LPGPC) [13], and molecular oxygen (LPGPO) [9]. Based on these various studies, the functional properties of such treated water could be applied to agriculture and various branches of industry, as well as human and animal prophylaxis and therapy.…”

Effects of a Plasma Water and Biostimulant on Lawn Functional Value

“…Following the invention of LPGP and a generator suitable for treatment of water [37,38], a number of papers were published. They dealt with specific physical and physicochemical properties of water treated with LPGP in atmospheric conditions (LPGPA) [35], but also under oxygenfree nitrogen (LPGPN) [38], ammonia (LPGPAM) [39], methane (LPGPM) [40], carbon dioxide (LPGPC) [34], and molecular oxygen (LPGPO) [38].…”

Structure and some physicochemical and functional properties of water treated under ammonia with low-temperature low-pressure glow plasma of low frequency

“…These properties depended, among others, on the time of exposure of the water to GP and the atmosphere under which the GP treatment was performed. Thus far, the effect of the air [6], oxygen-free nitrogen [7], carbon dioxide [8], methane [9] and oxygen [10] upon results of the GP treatment was published. In the course of our studies, we found that the energy of applied GP never broke valence bonds and could not initiate any chemical reaction.…”
