摘要

在小型石英毛细管中成功合成了包覆银纳米颗粒的单片固相微萃取二氧化硅吸附剂。在顶空微萃取模式下，使用各种芳香族化合物对吸附剂进行测试，然后进行气相色谱分析。由于被分析物芳香体系与固定在吸附剂表面的银粒子之间的π-π电子相互作用，被分析物成功地从样品顶空中提取并通过气相色谱分析测定。

Synthesis and investigation of silver-coated monolithic solid phase microextraction silica sorbent

Monolithic solid phase microextraction silica sorbent coated with silver nanopar ticles (Ag NPs) was successfully synthesized in a small quartz capillary. The sorbent was tested in a headspace microextraction mode using various aromatic compounds followed by gas chromatography analysis. Due to the π-π electronic interaction between analytes aromatic systems and silver particles immobilized on the sorbent surface, the analytes were successfully extracted from a sample headspace and determined by gas chromatographic analysis.
