Determination of palladium by ET-AAS after previous preconcentration by solid phase extraction
Hajdová, Jana ; Čelechovská, Olga (referee) ; Komendová, Renata (advisor)
The theoretical part of this master’s thesis focuses on the characteristic of Palladium, his uses in the automotive convertors, the occurrence in the environment, bioaccumulation and human health risks. Next there are described the basics of biomonitoring and summarize suitable biomonitoring method for capturing airborne dust. There are also evaluated appropriate methods for preconcentration and determination of Palladium. The aim of experimental part of this thesis is description and evaluation optimalization preconcentration method SPE by using sorbents silicagel C18 and QuadraSil TA. Optimization of method conditions of electrothermal atomic absorption spectrometry (ET – AAS). The determination of Palladium using optimal conditions follows in real samples in the form of exposure lichen (Hypogymnia physodes) by automobile traffic in Brno.

Palladium in the environment
Hajdová, Jana ; Řezáčová, Veronika (referee) ; Komendová, Renata (advisor)
This work is focused on palladium in the environment. Its use is especially in the automobile industry as catalytic converters of motor vehicles, but also is applied in dental, jewelry making and electrical appliances. The release of this metal from automobile catalysts is getting into all environmental compartments (soil, road dust, water, plants), where goes to its accumulation. It can be a part of the food chain and cause health risks to humans. The work also focuses on methods of sampling, preconcentration and methods, which can determined palladium in environmental samples (spectrophotometric methods, AAS, ICP-AES and ICP-MS).
