AB  - Metal azolate frameworks (MAFs) as a subfamily of metal-organic frameworks (MOFs) 
      have received much attention in analyzing organic volatiles owing to their 
      remarkable structures. In this work, the headspace solid-phase microextraction 
      (SPME) fiber based on MAF-66 has been fabricated by a layer-by-layer deposition 
      method. To evaluate the performance of the MAF-66-coated fibers, polycyclic 
      aromatic hydrocarbons (PAHs) were tested as analytes with gas chromatography 
      (GC). Relevant experimental parameters were optimized including extraction 
      temperature, extraction time, desorption temperature, desorption time, the 
      stirring rate and salt concentration. Under optimum condition, PAHs including 
      naphthalene, 2-methylnaphthalene, 1-methylnaphthalene, acenaphthylene, 
      acenaphthene, fluorene and phenanthrene were detected with good linear range 
      (0.01-100 mug L(-1)), low detection limits (0.1-7.5 ng L(-1)), high enrichment 
      factors (123-3108) and relative standard deviations (RSDs) ranging from 0.23% to 
      4.2%. Additionally, the fiber exhibited a long lifetime with repetitively used 
      more than 270 times. The proposed method was also successfully applied for the 
      determination of PAHs in environmental samples and food samples.
