title: In situ solvothermal synthesis of metal-organic framework coated fiber for highly sensitive solid-phase microextraction of polycyclic aromatic hydrocarbons.
abstract: The present work reported a facile and simple in situ solvothermal growth method for immobilization of metal-organic framework UiO-66 via covalent bonding on amino functional silica fiber for highly sensitive solid-phase microextraction (SPME) of ten polycyclic aromatic hydrocarbons (PAHs) by coupling with gas chromatography-mass spectrometry (GC-MS) analysis. The developed SPME coated fiber has been characterized through SEM, TGA and XRD, confirmed the coating thickness of ∼25μm with high thermal and chemical stability. Under optimized conditions, the obtained method exhibited satisfactory linearity in range of 1.0-5000.0ngL(-1) for all the PAHs. The low detection limits were from 0.28ngL(-1) to 0.60ngL(-1) (S/N=3). The UiO-66 coated fibers showed good repeatability (RSDs less than 8.2%, n=5) and satisfying reproducibility between fiber to fiber (RSDs less than 8.9%, n=5). This method was successfully used for simultaneous determination of ten PAHs from Minjiang water and soil samples with satisfactory recoveries of 87.0-113.6% and 83.8-116.7%, respectively. Experimental results shows that the chemical bonding approach has dramatically improve the stability and lifetime of pure MOFs coating for SPME in sample pretreatment.
