Determination of selected hormonal drugs using liquid chromatography with mass detection
Jurasová, Lenka ; Lisá, Hana (referee) ; Vávrová, Milada (advisor)
This master’s thesis is focused on optimizing of the analytical method for the determination of selected drugs - estrone, estradiole, ethynylestradiol, estriole, diethylstilestrole, norethindrone, mestranole and progestrone in wastewater using liquid chromatography with mass spectrometry (LC/MS). Solid phase extraction (SPE) using Oasis HLB cartridges was chosen extraction method Different mobile phase, temperature, flow rates and mobil phase gradient were during the process of optimization. Samples of the wastewater were collectedat the inflow and outlow of the wastewater treatment plant in Břeclav and in University of Veterinary and Pharmaceutical Sciences Brno. Drugs were isolated from wastewater and preconcentrated using solid phase extraction (SPE) and determined by high performance liquid chromatography with mass spectrometric detection (HPLC/MS).

Determination of hormones in wastewater
Zouharová, Kamila ; Tulková, Tereza (referee) ; Vávrová, Milada (advisor)
The presented theoretical and practical study was focused on a single unit of drugs – hormones. In the present study were characterized in detail hormones as drugs or medical ressource and their mode of effect on the human body. Another important part of this study was focused on the evaluate of the incidence of estrogens in the environment and their possible impact on the aquatic ecosystem, mainly for waste water. The last part of study was processed analytical problems of determination of hormones. There were introduced pre-analytical and analytical methods – methods of isolation of hormones from the waste water and methods of thein final determination, which were based mainly on the separation processes.
