UV-photochemical volatile compounds generation from selenium species

Popis výsledku v původním jazyce

The contribution summarizes the results of TiO/UV-photochemical vapour generation of volatile form of Se from various selenium species. This emerging method of vapour generation uses the knowledge achieved in the water treatment processes for a very sensitive determination of Se species. It is particularly efficient in the determination of inorganic selenium; very good limits of detection in the pg.mL(-1) region were obtained for selenate and selenite with QT-AAS detection. Nevertheless this technique is also suitable for very sensitive determination of organic Se species. The methods accuracy was assessed by the analysis of spiked matrices (groundwater and mineral water samples) and by an interference study. Furthermore, experiments were carried out to find the wavelength and energy responsible for the UV-photo chemical generation of Se volatile compound and to obtain some information about the reactions taking place during the reduction/generation process.
