Structural stury of carboranes by mass spectrometry
Navrátilová, Romana ; Vávrová, Milada (referee) ; Čáslavský, Josef (advisor)
Boron cluster compounds are substances clearly synthetic, which don't exist outdoors. This group covers boranes, heteroboranes and their derivatives. They are synthesized and examined mostly for their extraordinary structural and bonding properties. Their study also brought many remarkable findings and even allowed practical use of these compounds in science and technology. This thesis is focused on the application of mass spectrometry for the identification of boranes and heteroboranes and on the study of their fragmentation mechanisms using tandem mass spectrometry on spherical ion trap.

Determination of macrolides in wastewater during the technology applied to wastewater treatment plants
Landová, Pavlína ; Čáslavský, Josef (referee) ; Vávrová, Milada (advisor)
Diploma thesis is focused on determination of macrolide antibiotics in wastewater. Environmental contamination with drugs currently represents a major problem. To determine the level of contamination is necessary to develop the appropriate analytical techniques. From the group of macrolide antibiotics were selected four representatives: erythromycin, clarithromycin, azithromycin and roxithromycin due to their frequent use in Czech Republic. For their isolation from wastewater was selected solid phase extraction and for analysis high performance liquid chromatography with mass spectrometric detection was chosen. Under optimized conditions, the ten days analysis of wastewater from the WWTP Brno-Modřice, two days analysis of wastewater from the WWTP Mikulov and one day analysis of wastewater from WWTP of University of Veterinary and Pharmaceutical Sciences Brno was performed.
