Abstract

Dielectric studies were conducted over the ranges 200 Hz to 1 MHz and 260 K to 298 K on Na** plus , K** plus , Rb** plus , Cs** plus , NH//4** plus and CH//3NH** plus //3 forms of synthetic Linde A-type zeolite. The water content of the samples was controlled by standardized drying. Permittivity and loss factor were measured in suspensions of zeolite with paraffin oil. The relaxation process was described by the Kirkwood-Fuoss relation and the distribution parameters ( beta and omega //m//a//x) were determined. Arrhenius activation energies were calculated from the temperature dependence of omega //m//a//x. Comparison of the effective dipole moment and that derived from the Onsager theory indicates relaxation of water.
