Application of Solid Phase Microextraction Fiber Coated with Single-walled Carbon Nanotubes in the analysis of Aqueous Samples

Abstract

固相微萃取(SolidPhaseMicroextraction,SPME)技术具有操作简单、分析时间短、样品需要量少、无需萃取溶剂、可与气相色谱和高效液相色谱在线联用等优点,是环境样品分析中备受关注的一种样品预处理技术。现有的商品化SPME纤维普遍存在耐高温性能差,耐有机溶剂性能不佳,涂层的化学稳定性差,使用寿命短等缺点。近年来,国内外许多科研工作者研制了很多新型的SPME纤维,但这些自制纤维只解决了商品化纤维存在的部分问题。因此,发展新型萃取纤维是SPME技术发展的关键。 本文利用电泳沉积法(ElectrophoreticDeposition,EPD)制备了以单壁碳纳米管(Single-W...Solid phase microextraction (SPME) has been widely applied in sampling and analysis of environmental samples due to its simplicity, solvent free nature and feature of easy coupling to GC and HPLC. However, the commercial SPME fibers present drawbacks such as low operating temperature, instability in organic solvents, poor chemical stability and limited lifetime.
