Investigation of transport processes in humic systems using computer modelling
Zeman, Matěj ; Sedláček, Petr (referee) ; Smilek, Jiří (advisor)
This bachelor’s thesis deals with issue of humic acid diffusion. The main goal of this work is to obtain a simple mathematical model that simulates the dialysis of a dye and humic acid and thus to investigate the bonding properties of humic acids as a sorption agent. This model was simplified enough to be used as a basis for the next modelling. The COMSOL Multiphysics program was used to create the model, especially the „Transport od Diluted Species“ and „Chemistry“ modules, which enable simulation of the mentioned processes. The results showed that it is possible to monitor dialysis over time using this model and at the same time the sorption properties of these substances can be observed.
