Abstract

Treatment of water saturated with CO2 with low-temperature, low-pressure glow plasma of low-frequency (GP) produced a series of liquids. Their temperature and intensity of thermal effects non-linearly depended on the treatment time. However, the Raman spectra patterns of the treated water pointed to a specific structure of the water treated for 30 min. The spectra of control, non-treated water saturated with CO2, and such water treated for 15, 60, 90, and 120 min showed that their macrostructure was built mainly by a single donor, and single hydrogen bonded arrangements accompanied, to a certain extent, with free water molecules. The macrostructure of the water treated for 30 min consisted chiefly of tetrahedral and deformed tetrahedral structural units. That water contained long-living free radicals of discussed structure, stabilized in such macrostructure.

Highlights

  • Our recent papers have presented macrostructure and properties of water treated with low-temperature and low-pressure glow plasma of low-frequency (GP) in the air [1] as well as under pure nitrogen [2], ammonia [3], and methane [4]

  • CO2 as well as the evolution of methane from its aqueous clathrates [17,19]. Such direction of the application of aqueous CO2 clathrates underlined the importance of our studies presented in this paper

  • The original pH of non-treated water saturated with CO2 was practically insensitive to the GP treatment (Table 2)

Summary

Introduction

Our recent papers have presented macrostructure and properties of water treated with low-temperature and low-pressure glow plasma of low-frequency (GP) in the air [1] as well as under pure nitrogen [2], ammonia [3], and methane [4]. Nanowater stimulates various fermentative microorganisms, biopesticides and drastically influences the production of essential oils by herbs, control breeding plants, and animals Such applications have been recently reviewed in our recent paper [5]. Physicochemical studies [1,2,3,4,5] have revealed that in every case, the treatment of water with GP results in declusterization of the water macrostructure, and molecules of gases dissolved in the treated water are excited. In such states, they are closed inside aqueous clathrates. The extent to which water is declusterized and the structure of resulting clathrates, as well as their excited guest molecules, depend on the treatment time and
