The Effect of Water Treatment by the Ultrahigh Frequencies Electromagnetic Field on the Relative Viscosity of Aqueous Solutions of Na-Carboxymethylcellulose
Abstract
A significant increase in the relative viscosity of 0.5% solutions of Na-carboxymethylcellulose was found when water, exposed to the electromagnetic field of the radiofrequency band (110-170 MHz), was used as a solvent. It is shown that the efficiency of the electromagnetic action depends on the frequency of the field — the maximum change in the viscosity of the solutions corresponds to the frequencies 130 and 170 MHz. The effect of pH and temperature on the viscosity of these solutions was studied. It is shown that an increase in pH from 3 to 7 is observed. The viscosity is maximal at pH = 7 ... 9, further increase in pH leads to its decrease. The observed dependence is due to conformational changes in polymer macrocoions due to a change in their charge characteristics. The type of dependence on pH is the same for irradiated and nonirradiated systems, however the degree of viscosity increase depends on pH and temperature. Investigations were carried out in the temperature range 278-303 K. As the temperature increases, the viscosity of the solutions decreases, but for solutions prepared in irradiated EMF water, it exceeds the viscosity of the control samples in the studied temperature range. At T = 298 K and pH = 11, it increases by 59% (field frequency 130 MHz) compared to the control sample. The observed phenomena may be caused by the weakening of the solvation of the hydrophilic groups of the polymer in irradiated water and the increase in the rigidity of the chain of macromolecules due to the formation of intra- and intermolecular hydrogen bonds.
