AB  - In this study, we report a facile, environmental friendly fabrication of a type 
      of magnetic metal-organic framework (MOF) MIL-100 that can be used for magnetic 
      solid-phase extraction (MSPE). The magnetic MOF composites were fabricated using 
      in situ calcination method. The as-synthesized materials exhibited both high 
      porosity and magnetic characteristics. They used for the MSPE of polycyclic 
      aromatic hydrocarbons (PAHs) from water samples. Such MOF-based magnetic 
      solid-phase extraction in combination with gas chromatography equipped with a 
      flame ionization detector (GC-FID), exhibited wide linearity (0.02-250mugL(-1)), 
      low detection limits (4.6-8.9ngL(-1)), and high enrichment factors (452-907) for 
      PAHs. The relative standard deviations (RSDs) for intra- and inter-day 
      extractions of PAHs were ranging from 1.7% to 9.8% and 3.8% to 9.2%, 
      respectively. The recoveries for spiked PAHs (1mugL(-1)) in water samples were in 
      the range of 88.5% to 106.6%. The results showed that the special anion-pi orbital 
      (electron donor-acceptor) interaction and pi-pi stacking between magnetic MIL-100 
      and PAHs play an important role in the adsorption of PAHs.
