AB  - A nitrogen-doped metal organic framework (MOF) based porous carbon 
      (C-(C(3)N(4)@MOF)) was produced by the carbonization of a graphitic carbon 
      nitride (g-C(3)N(4)) templated MOF (NH(2)-MIL-125). The C-(C(3)N(4)@MOF) was then 
      coated on a stainless steel wire by sol-gel technique to serve as a solid-phase 
      microextraction (SPME) fiber coating. The coated fiber was studied for the 
      extraction of fourteen organophosphorous pesticides (OPPs) from different fruit 
      and vegetable samples followed by gas chromatography-mass spectrometer (GC-MS) 
      detection. The C-(C(3)N(4)@MOF) coated fiber exhibited a high extraction 
      capability for the OPPs. Both single factor optimization and response surface 
      analysis (Box-Behnken Design) methods were implemented to optimize the experiment 
      conditions for the extraction. The results indicated that the linear response for 
      the fourteen OPPs was in the range from 0.69 to 3000 ng g(-1) and the 
      coefficients of determination (r(2)) ranged from 0.9981 to 0.9998. The limits of 
      detection (LODs, S/N = 3) ranged from 0.23 to 7.5 ng g(-1). The method recoveries 
      (R) of the fourteen OPPs for spiked fruit and vegetable samples were between 
      82.6% and 118%, with the relative standard deviations (RSDs) varying from 2.8% to 
      11.7%. The fiber can be reused over 100 times without a significant loss of 
      extraction efficiency.
