Resum:
The objective of this Doctoral Thesis is the evaluation of the novel sorptive extraction techniques, such as fabric phase sorptive extraction (FPSE), dynamic FPSE, (CPME) and dispersive solid-phase extraction (d-SPE) using hypercrosslinked magnetic particles (MPs) for the extraction of different emerging organic contaminants of a wide range of polarity from environmental water samples. In the first section, FPSE with two different extraction modes, static and dynamic, were evaluated to extract a group of pharmaceuticals and personal care products. In the second section, a recently introduced CPME technique was evaluated for a group of personal care products; and, in last section, MPs with hypercrosslinked properties were employed for the extraction of sweeteners using d-SPE technique. In all methods developed liquid chromatography followed by tandem mass spectrometry (LC-MS/MS) was used for the determination of the contaminants. The evaluation of these techniques showed that they are alternative extraction techniques and encourage us to test them for different types of analytes in different kind of samples.
