UV-Photochemical Generation of Volatile Compounds for Determination of Se in Selected Nutrition Supplemets
Kolorosová, Alžběta ; Červený, Václav (advisor) ; Kratzer, Jan (referee)
The option of UV-photochemical generation of volatile compounds coupled with atomic absorption spectrometry for the determination of selenium in the real samples (pills) is described in this work. The optimum conditions of UV-photochemical generation of volatile compounds was investigated. After that the limit of detection as low as 58 ppt for Se+IV and 30 ppt for Se+VI was obtained. The nutrition supplement, which contain selenium, was choosen and analyzed by this method. Iodide and cupric interfere the determination of selenium in the real samples.
