Přítomnost singletového kyslíku v povrchových vodách
KOVAŘÍKOVÁ, Michaela
This master thesis deals with the methods of measurement of singlet oxygen steady state concentrations in surface water and the factors affecting this concentration. The first part of this work shows theoretical background and an introduction to photochemistry of surface water with respect to the reactive oxygen species. The second part describes the methodology of conducted experiments and discuss its results with respect to current literature.
Photochemical formation of the low-molecular-weight organic acids
KOVAŘÍKOVÁ, Michaela
This thesis deals with photochemical decomposition of dissolved organic matter (DOM) in surface waters. Intermediate products were identified using HPLC separation technique and the kinetics of formation and decomposition was modeled in a system unaffected by the presence of bacteria. The influence of various factors such as pH and age of DOM was tested.
