摘要：

超分子溶剂是两亲化合物通过分子间有序的自组装过程形成的具有纳米结构的胶束聚集体，是一种高效提取溶剂。该文以高效液相色谱-荧光检测法为测试手段，系统地对超分子溶剂组成及用量进行了优化，发展了一种直接提取、快速测定水中多环芳烃的方法，并进行了方法学验证及实际样品检测。结果表明，采用四氢呋喃和1-辛醇制备的超分子溶剂对4种多环芳烃的回收率为89.08%~102.47%，相对标准偏差（RSD， n=5）为1.38%~3.92%。4种多环芳烃在一定范围内线性关系良好（相关系数R2>0.999），检出限为1.26~9.23 ng/L。该方法前处理过程简单，有利于实现快速分析；溶剂使用量少，符合绿色化学的发展趋势，具有一定的推广价值。

Abstract:

Supramolecular solvent (SUPRAS) is a nano-structured liquid generated from amphiphiles through a sequential self-assembly process. It is an efficient and excellent solvent for the sample extraction. In this paper, a method to directly extract and rapidly analyze polycyclic aromatic hydrocarbons (PAHs) in water samples by high performance liquid chromatography-fluorescence detection (HPLC-FLD) was developed. The composition and amount of SUPRAS were optimized and practical samples were tested. It indicated that the combination of tetrahydrofuran and 1-octanol was a suitable SUPRAS for the extraction of four PAHs with recoveries between 89.08% and 102.47% and relative standard deviations (RSDs) from 1.38% to 3.92% (n=5). Results showed a good linearity of four PAHs with the correlation coefficients (R2) more than 0.999. The limits of detection (LODs) ranged from 1.26 to 9.23 ng/L. The proposed pretreatment method greatly reduces the analysis time. And the solvent-less approach is in accordance with the development trend of green chemistry and of great application prospects.
