Mathematical modelling diffusion of metal ions in humic gel
Masár, Lukáš ; Ing. Eva Gregorová,CSc. (referee) ; Klučáková, Martina (advisor)
The subject of this bachelor thesis was simulation of diffusion processes proceeding in the reactive gelous media using the COMSOL Multiphysics software. The aim of this study was to develop a comprehensive set of models available for the interpretation of experimental data obtained in the study of metal ions transport in the humic acids hydrogel. The main consideration was given to the influence of porosity modelling and chemical interactions on the diffusion characteristics (mainly diffusion flow). Within the simulation of the influence of chemical reactions, different kinetic models were used (one-way reaction of first and second order and reverse reaction).
