Fotochemická degradace parabenů
FREJLACHOVÁ, Kristýna
The aim of this master thesis was to investigate a photochemical degradation of three representatives of parabens (methylparaben, ethylparaben and propylparaben) in aqueous solutions. Two experimental arragements were adopted in the study: a heterogeneous photocatalytic process on an immobilized TiO2 and a reaction in a homogeneous mixture; in the latter arrangement, the effect of Fe(III) concentrations was examined.
Phosphorus sorption on photochemically induced particles
FREJLACHOVÁ, Kristýna
This Bachelor thesis studies sorption of phosphorus on photochemically induced particulate matter. Theory part is about the forms of phosphorus and organic matter in water and summaries coprecipitation of phosphorus and organic matter. Experiments deal with the formation of particulate matter and its composition with regards to initial concentration of aluminium and iron. The sorption of radioactive 33P on newly formed particles is tested.
