Abstract:

The microwave dielectric properties of aqueous solutions of the ammonium heptamolybdate (AHM)-poly(vinyl alcohol)-water ((NH4)(6)Mo7O24-PVA-water) system are studied along sections with constant concentrations of the components in the frequency region in which the dispersion peak of the dielectric constant of water falls (13-25 GHz) at 298 and 313 K. The static dielectric constant epsilon(s) and the dielectric relaxation time tau of the solutions are found. The dielectric characteristics along the sections vary additively as a function of concentration with respect to the relationships observed in the AHM-water and PVA-water binary systems. The rotational mobility of water molecules is mainly controlled by polymer additives. We suggest that two (water and polymer-ion) subsystems exist in the solution in this case; these subsystems only weakly affect each other.
