Options determination of synthetic fragrances in wastewater
Kašparová, Jarmila ; Zlámalová Gargošová, Helena (referee) ; Vávrová, Milada (advisor)
Synthetic fragrances (musk) are artificially made organic compounds, which are used as fragrances in pharmaceutical and cosmetic products. The presence of musk is proven in all environmental compartments. However, the greatest attention is paid to purified waste water, which is a frequent source of pollution of surface water. The physico-chemical properties of musk compounds cause their accumulation in the living and non-living components of the ecosystem, where they behave as persistent pollutants. The presented bachelor thesis deals with the problem of determining individual musk compounds of all groups side by side. In the bachelor thesis, nineteen musk compounds of four groups, nitromusk compounds, macrocyclic musk compounds, linear musk compounds, polycyclic musk compounds were studied. The basis of this work was to optimize the method for determining all groups of musk compounds side by side, evaluating and interpreting the results. Solid phase microextraction (SPME) was used as a method for extracting analytes. Gas chromatography in conjunction with mass spectrometry was used for the final analysis, as a detector was used for a Time of flight analyzer.
