Abstract

V delu je predstavljena karakterizacija mešanic gline in vode na podlagi dielektrične spektroskopije in analiza pridobljenih spektrov. Predlagan je teoretičen model dinamike ionov, ki poleg gibanja ionov v porah elektrolita vključuje tudi njihovo ujetost na površinah mineralov. Časovne konstante, ki določajo dinamiko teh pojavov, so povezane z fizikalnimi lastnostmi snovi. Mikroskopsko gibanje ionov v kompleksnem okolju mešanice gline in vode lahko opišemo z dinamiko delcev, ki vodi do subdifuznega obnašanja.

Secondary title: Ugotavljanje značilnosti dinamike ionov v mešanici gline in vode s pomčjo dielektrične spektroskopije
Secondary abstract: Dielectric spectroscopy characterization of clay-water mixtures is presented and the obtained spectra are analysed. A theoretical model for ion dynamics isproposed in which motion of ions in pore space electrolyte is interrupted by trapping events at the mineral surfaces. The typical time scales for these processes are given in terms of the physical properties of the material. It isshown that the microscopic motion of the ions in a complex environment of clay-water system can be described with fractional dynamics leading to subdiffusive behavior.
