Study on reactivity of humic acids via method of diffusion cells
Hrubá, Pavla ; Weidlich,, Tomáš (referee) ; Sedláček, Petr (advisor)
The diploma thesis focuses on utilization of diffusion cells in reactivity mapping study on humic acids. In the experimental part, samples 6 humic acids of different origin or chemical modification were studied. All the samples were characterized by basic analytical and physico-chemical methods (elemental analysis, thermogravimetry, determination of acidity, spectrometry). Methylene blue was utilized as a model reactive probe and agarose gel as an inert support medium. An effect of interactions between humic acids and methylene blue on diffusivity of the dye in the hydrogel was determined and discussed.
Study of diffusion of cupric ions in humic gel by methods of diffusion cells
Hrubá, Pavla ; Gregorová, Eva (referee) ; Klučáková, Martina (advisor)
This bachelor’s thesis is focussed on study of diffusion of cupric ions in humic gel by diffusion cells policy. The aim of this work was to introduce the diffusion cells to examination of transport metal ions in humic gels and to compare reached accomplishments with last diffusion’s experiments. The main advantage of this experimental technic was an automatization of all the gauging operation.
