Ordered mesoporous materials have received a great deal of attention, as a novel mesoporous material, M41S, was firstly reported by researchers in the Mobil laboratory in the early 1990s, because of their potential applications in catalysis, separation technology, nanoscience, and biomaterials. Compared with microporous materials, mesoporous materials not only have larger surface area (up to 1500 m2/g) and thicker wall between pores, uniform pore size distribution (-1.5-40 nm) and huge pore volume, but also they have excellently mechanical and chemical stability. They were widely used as catalysts, sorbents and separation materials in the past decade. Up to now a great variety of functionalized and morphologic momesoporous materials have been developed in order to obtain higher selectivity and special action sites.Solid-phase microextraction (SPME) as a new solvent-free extraction technique in sample preparation appeared in the early 1990s. Because of its advantages of simplicity, rapid extraction and easy quantification, SPME was successfully applied to extracting and concentrating for various analytes in environmental samples (gas, liquid, solid), foodstuff, biological samples and materia medica. SPME could be easily coupled with the apparatus, such as gas chromatography (GC) and high performance liquid chromatography (HPLC). Fiber with coating is the most important part of SPME, the selectivity and the extraction efficiency of the fiber depend considerably on the coating materials. Up to date many experimental coatings have been prepared and investigated for a wide range of applications. The coating materals that were universally used in SPME are various polymer-based coatings, such as polydimethylsiloxane (PDMS) and polyacrylate (PA), which were coated on fused silica fibers. However, specialized materials have been also developed for special demand in SPME. In this dissertation, our effort is to synthesize new functionalized mesoporous materials and use as coating materials in SPME for analysis of environmental samples by high-performance liquid chromatography coupling with SPME technique.The dissertation consists of six parts:
