摘要

立陶宛维尔纽斯Naugarduko街24号维尔纽斯大学分析与环境化学系，邮编03225单片二氧化硅固相萃取柱已成功应用于柴油和石油基质中苯并[a]芘的快速分馏和随后的气相色谱分析。由于吸附剂表面的银纳米颗粒与芳香族分析物之间的π-π电子相互作用，实现了特定的保留。已经证明，仅0.2g吸附剂和6ml有机溶剂就足以进行这种分离。

Silver-coated monolitic silica column for separation of benzo[a]pyrene from petroleum

Department of Analytical and Environmental Chemistry, Vilnius University, 24 Naugarduko Street, 03225 Vilnius, Lithuania Monolithic silica solid-phase extraction column has been successfully applied for the rapid fractionation and subsequent gas chromatographic analysis of benzo[a]pyrene from the diesel and oil matrix. Due to π-π electronic interactions between silver nanoparticles on the sorbent surface and aromatic analyte specific retention was achieved. It was demonstrated that only 0.2 g of the sorbent and 6 ml of the organic solvent are enough for such separation.
