Sorption of charged organic compounds on humic acids
Krist, Tomáš ; Doskočil, Leoš (referee) ; Enev, Vojtěch (advisor)
Bachelor thesis deals with a sorption properties and physical-chemical characterization of humic acids before and after the adsorption. Sorption experiments with a methylene blue and a rhodamin 6G were performed. Adsorption isotherms were obtain via UV/VIS spectrometry. The Langmuir isotherm was used to evaluate the experimental data. Standard of HA isolated from Leonardite was characterized by an elemental and thermogravimetric analysis, by a Fourier-transform infrared spectroscopy, a surface area analysis and also by a potentiometric titration.

Methylene Blue Test for Plasticity Determination of Brick Clays
Jiroušek, Štěpán ; Stančík,, Hynek (referee) ; Sokolář, Radomír (advisor)
The Bachelor thesis is focused on methods for assesing the plasticity of ceramic raw materials (clays). The theoretical part describes the origin, species, chemical and mineralogical composition of these raw materials. Then we describe the preparations and standardized and nonstandardized methods of assesing the plasticity of clay used in the Czech Republic and abroad. The practical part describes executed tests of brick soils specimen used in the Czech Republic. The outcome of this work is to find correlations between these tests and the determined value of sorption of methylen blue.
