| 英文摘要 | A nanoporous array anodic titanium-supported co-polymeric ionic liquids (NAAT/PILs) solid-phasemicroextraction (SPME) fiber was prepared in situ on the titanium wire. NAAT was selected as the sub-strate, in view of its high surface-to-volume ratio, easy preparation, mechanical stability, and rich titanolgroups on its surface which can anchor silica coupling agent containing vinyl and then introduce ionicliquid copolymers as sorbents. In this work, 1-vinyl-3-nonanol imidazolium bromide ([C9OHVIm]Br) and1,4-di(3-vinylimidazolium) butane dibromide ([(VIM)2C4]2[Br]) were synthesized and used as monomerand crosslinker, respectively. Extraction properties of the NAAT/PILs fiber for polar alcohols and volatilefatty acids (VFAs) in aqueous matrix were examined using gaseous sampling–SPME (GS–SPME) andheadspace SPME (HS–SPME) mode, respectively. Combining the superior properties of NAAT substrateand the strong hydrogen bond interaction of PILs to polar compounds, the NAAT/PILs SPME fiber showedmuch higher adsorption affinity to aliphatic alcohols than bare NAAT and pure PILs fibers. The detectionlimits (LOD) of established GS–SPME–GC–FID method are in the range of 0.35–17.30 ng L−1with a linearrange from 0.01 to 500 ng mL−1. Also, it showed high extraction performance toward volatile fatty acids(VFAs) compounds from aqueous matrix. Under the optimized SPME conditions, wide linear ranges wereobtained with correlation coefficients (R2) greater than 0.99 and limits of detection were in the range of0.85–8.74 ng L−1. Moreover, real-world samples were analyzed and good results were obtained. |
