Abstract: The objectives of this study are to develop one type of microextraction methodologies, i.e. liquid-phase microextraction (LPME) and to explore and extend its range of applicability in environmental analysis. Firstly, organic solvent-based hollow fiber-protected LPME was coupled with on-column derivatization to determine carbamate pesticides and pharmaceutically active compounds (PhACs) present in environmental aqueous samples. The results suggested that hollow fiber-protected LPME coupled with on-column derivatization represented an excellent sample preparation method for the analysis of polar or thermally-labile organic pollutants or drugs in environmental water samples.Secondly, water-based and ionic liquid-based LPME techniques were developed. These two LPME techniques opened new perspectives in the development of LPME methods since they were not only effective but also totally organic solvent-free.
