Aplication of ICP-MS in environmental analysis and possibilities of this technique for the determination of silicon in waters
Bohdálková, Veronika ; Doležalová Weissmannová, Helena (referee) ; Čáslavský, Josef (advisor)
This bachelor thesis is focused on the application of inductively coupled plasma mass spectrometry (ICP-MS) in environmental analysis. This method offers multi-element analysis on trace and ultra-trace levels as well as isotopic analysis of various species in diverse matrices like drinking, surface and waste waters, sediments, biological samples, food and others. ICP-MS due its high sensitivity, ability of parallel determination of many elements and speed of analysis is more and more applied in the field of pollution control and environmental protection. The main goal of this bachelor thesis is the evaluation of the possibility of silicon determination in various kinds of water by ICP-MS.
Question of determination of analgetics in waters
Benešová, Markéta ; Lisá, Hana (referee) ; Vávrová, Milada (advisor)
The bachelor thesis is focused on the optimization of the method for the determination of analgetics in waters. The aim of this work is to work up the methodical procedure for determination of chosen pharmaceuticals i.e. salicylic acid and naproxen in model water samples. Analytes were isolated by solid phase extraction (SPE); they were identified by high performance liquid chromatography with UV-VIS detection of diode – array type (HPLC – DAD). The optimal method was selected from several verified procedures on the basis of practical experience.

Occurence of lignans in environmental waters
Tříska, Jan ; Moos, Martin ; Marešová, I. ; Vrchotová, Naděžda
The content of lignans, especially hydroxymatairesinol (HMR) was investigated in different types of natural waters from the environment. Collected water samples were extracted with methyl tert. butylether, derivatized and analysed by means of GC-MS. HMR was found in different amount in all water samples beside the other lignans.
