Structure and Physicochemical Properties of Water Treated under Carbon Dioxide with Low-Temperature Low-Pressure Glow Plasma of Low Frequency

Treatment of water saturated with CO<sub>2</sub> 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 t...

Description
Summary:Treatment of water saturated with CO<sub>2</sub> 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 CO<sub>2</sub>, 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.
