Abstract: With the trend of miniaturization in analytical chemistry, microextraction is now an active research field with advantage of easy handling, speed, economy and compatibility with the low injection volumes of modern analytical instruments. This research work focused on the development of novel microextraction techniques and their applications to environmental sample analysis. The new microextraction techniques included developing a new type of fiber for solid phase microextraction , solvent bar microextraction (SBME), dynamic hollow fiber-supported headspace solvent microextraction (DHF-HS-SME), and dynamic liquid-liquid-liquid microextraction with the automated movement of the acceptor (final extracting) phase (LLLME/AMAP). Throughout this work, the results explicitly demonstrated that the newly developed microextraction techniques can be efficiently employed to the analysis of environmental pollutant in aqueous solutions and soil or slurry samples. In addition, all these new techniques are easily compatible with modern analytical equipments such as GC, GC/MS or HPLC.
