It was established that low intensity exposure (1 W) ultra-high frequency electromagnetic fields (175–265 MHz) for the water leads to a change in its physical-chemical properties. It has been shown that a significant increase in the electric conductivity and pH of the water occurs at a certain frequency of the field (180, 210, 220 and 230 MHz) and the time of exposure – 3 hours, which is interpreted as a change in its supramolecular organization. A substantial reduction in the relative viscosity of a 0,2% alkaline solution of CMC-Na, prepared with water having been exposed to electromagnetic, it is most pronounced for the frequencies 210 and 220 MHz. The viscosity measurements were carried out in the temperature range 25–40 °C. The effect is maintained throughout the temperature range studied. From the temperature dependence of the viscosity is calculated activation energy of viscous flow. It established its decline compared with control samples. Showed a decrease in turbidity alkaline solutions Na-CMC, prepared on the water subjected to an electromagnetic field. The observed effects may be due to the more compact packaging of the macromolecules of the polymer due to the weakening of hydration as a result of the restructuring of the supramolecular structure of water under irradiation.
