- Resumen
The aim of this Doctoral Thesis is the development of novel polymeric materials for different sorptive extraction techniques, such as solid-phase extraction (SPE) and stir bar sorptive extraction (SBSE). Both techniques were applied in liquid-chromatography and tandem mass spectrometry (LC-MS/MS) for determining a group of emerging contaminants, such as pharmaceuticals, illicit drugs and personal care products, from wastewater samples. To improve the detection of these contaminants in several environmental samples at low levels of concentrations, extraction techniques have to enable a high enrichment factor and high selectivity towards the analytes of interest removing interfering compounds. In this Doctoral thesis, a molecularly imprinted polymer (MIP) specific for a group of non-steroidal and anti-inflammatory drugs (NSAIDs) and other polymeric material with strong cation-exchange behaviour were evaluated as sorbents for SPE. Moreover, different monolithic materials with a polar nature were also synthesised to be used as coatings for SBSE and as a result, favour the extraction of more polar compounds
