Study of chemical processes initiated by electrical discharge in liquids
Možíšová, Aneta ; Zlámalová Gargošová, Helena (referee) ; Kozáková, Zdenka (advisor)
This Bachelor´s thesis in the first part describes the process of ignition of the plasma discharge in water solutions, the generation of the particles that are generated during the discharge and their subsequent analysis by appropriate analytical methods. The second part focuses on specific cases of the use of the plasma discharge in the environment of selected electrolyte, phosphates were selected for individual experiments and for the comparison of sodium chloride. Phosphates were chosen mainly because of their stable pH as a possible benefit in discharge. The aim is to obtain the most ideal environment for the ignition of the plasma discharge and to optimize the method, which could subsequently be used for medical purposes, especially when sterilizing tools

Hydrogen peroxide generation by the microwave plasma jet
Staškovanová, Denisa ; Mazánková, Věra (referee) ; Kozáková, Zdenka (advisor)
This Bachelor thesis deals with the generation of hydrogen peroxide by the microwave plasma jet in distilled and tap water. The main goal was to characterize the amount of generated hydrogen peroxide depending on various experimental conditions and to determine its stability. A titanium reagent was used to determine if hydrogen peroxide was present in the sample. The method for determination of hydrogen peroxide concentration was spectrophotometry. In conclusion, differences in the concentration of hydrogen peroxide are formulated according to the change in experimental conditions, its stability in plasma activated water and stability in complex with the titanium reagent. Differences between the generation in distilled and tap water are also described.
