Evaluation of the contamination of working environment in the Gumotex Breclav joint stock company
Petrušová, Pavlína ; Vávrová, Milada (referee) ; Čáslavský, Josef (advisor)
Diploma thesis deals with the assessment of volatile organic compounds contamination of selected working environment in Gumotex, joint stock company using passive sampling. The theoretical part contains description of these compounds and their reactions in the atmosphere, practical use of these substances and their effect on human health. The possibilities of passive sampling and determination of these substances are described as well. The experimental part contains analysis of volatile organic compounds at two selected workplaces in Gumotex, joint stock company using passive samplers Radiello. Final determination by gas chromatography with flame ionization detector was preceded by adsorption surface extraction of sampler with carbon disulfide. In conclusion, obtained data are compared with the permissible exposure limits and maximum allowable concentrations, which are defined by the National Health Institute.

Organic Vapour Sorption and Permeation in Polymer Gel Membrane Containing Imidazolium Based Ionic Liquid
Morávková, Lenka ; Vopička, O. ; Vejražka, Jiří ; Vychodilová, Hana ; Sedláková, Zuzana ; Friess, K. ; Izák, Pavel
In this work, vapour sorption and transport properties were studied for the aliphatic hydrocarbon (hexane), branched hydrocarbon (isooctane), and alcohol (ethanol) using a gravimetric sorption apparatus and a home-made laboratory-scale apparatus, respectively. The ionic liquid polymer gel membrane based on poly(vinylidene fluoride-cohexafluoropropylene) (abbreviated p(VDF-HFP)) was prepared by solvent casting from a solution in acetone. The used membrane contains 80 wt. % of the imidazolium basedionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([emim][Tf2N]).
