Abstract: Micro-solid-phase extraction (?-SPE) approaches for the sample preparation of environmental aqueous samples are developed. Firstly, magnetic ?-SPE device used not only for extraction but also a stirrer bar was studied. A novel sorbent was synthesized and characterized for use in extraction of polycyclic aromatic hydrocarbons in environment water. Subsequently, double extraction method, ?-SPE followed by thermal extraction was investigated. Sorbent composite was prepared and used for the extraction of polybrominated diphenyl ethers in water by this procedure. Electro membrane extraction could be used for complex sample matrices, since the membrane containing extraction solvent can act as a filter to prevent the co-extraction of matrix interferences. Finally, electro membrane involving a porous membrane filled with electro conductive sorbent and supported liquid membrane was studied for the extraction of phenolic contaminants in water.
