摘要

为研究多环芳烃(PAHs)对海洋的污染,采用溶剂辅助配体掺入法合成了UiO-67/全氟辛酸(UiO-67/PFOA)。然后将 UiO-67/PFOA 作为吸附剂用于顶空固相微萃取(HS-SPME)技术,以收集和富集痕量多环芳烃。PFOA的加入提高了UiO-67/PFOA涂层的疏水性和稳定性,UiO-67/PFOA中的C-F官能团可与多环芳烃苯环上的CH形成假氢键,使UiO-67/PFOA对多环芳烃的富集性能是UiO-67的1.60-4.63倍。在最佳条件下,多环芳烃的线性范围宽(0.01-20 ng-mL-1),测定系数(R2 ≥ 0.9950)和检出限(LODs,0.003-0.008 ng-mL-1)均较低。该方法对加标海水和海底沉积物中5种多环芳烃的回收率为81.14%~116.0%,结果令人满意。该研究为在复杂环境中富集痕量多环芳烃提供了一种良好的吸附剂,也为后续合成具有良好富集性能的吸附剂提供了一种新方法。

Constructing perfluorinated UiO-67 for enrichment of polycyclic aromatic hydrocarbons in seawater and seabed sediments
To investigate the ocean contamination caused by polycyclic aromatic hydrocarbons (PAHs), UiO-67/perfluorooctanoic acid (UiO-67/PFOA) was synthesized through solvent-assisted ligand incorporation method. The UiO-67/PFOA was then served as an adsorbent in headspace solid-phase microextraction (HS-SPME) technology for collecting and concentrating trace PAHs. The addition of the PFOA improved the hydrophobicity and stability of the UiO-67/PFOA coating, and the C-F functional group in UiO-67/PFOA could form the pseudo hydrogen bonding with the CH on the benzene ring of PAHs, which endowed the UiO-67/PFOA with 1.60–4.63 times enrichment performance for PAHs than UiO-67. Under optimal conditions, the wide linear ranges of PAHs (0.01–20 ng·mL−1) with good coefficients of determination (R2 ≥ 0.9950) and low limits of detection (LODs, 0.003–0.008 ng·mL−1) were obtained. The recoveries of five PAHs from spiked seawater and seabed sediment by the developed method ranged from 81.14 % to 116.0 % with satisfactory results. This work provided a good adsorbent for the enrichment of trace PAHs in complicated environments and a new approach for the subsequent synthesis of adsorbents with good enrichment performance.

期刊介绍: The Journal of Chromatography A provides a forum for the publication of original research and critical reviews on all aspects of fundamental and applied separation science. The scope of the journal includes chromatography and related techniques, electromigration techniques (e.g. electrophoresis, electrochromatography), hyphenated and other multi-dimensional techniques, sample preparation, and detection methods such as mass spectrometry. Contributions consist mainly of research papers dealing with the theory of separation methods, instrumental developments and analytical and preparative applications of general interest.
