AB  - In this study, poly(ethylene glycol) (PEG) grafted multi-walled carbon nanotubes 
      (PEG-g-MWCNTs) were synthesized by the covalent functionalization of MWCNTs with 
      hydroxyl-terminated PEG chains. PEG-g-MWCNTs was used as a novel stationary phase 
      to prepare the sol-gel solid-phase microextraction (SPME) fiber in combination 
      with gas chromatography-flame ionization detector (GC-FID) for the determination 
      of ibuprofen, naproxen and diclofenac in real water samples. Some parameters 
      which influencing the extraction efficiency were such as desorption temperature 
      and time, extraction temperature and time, pH, salt effect and stirring speed 
      that were investigated and optimized. Under the optimal conditions, the method 
      detection limits (S/N=3) were in the range of 0.007-0.03 ng mL(-1) and the limits 
      of quantification (S/N=10) between 0.05 and 0.07 ng mL(-1). The relative standard 
      deviations (RSDs) for one fiber (repeatability) (n=5) were obtained from 5.9 up 
      to 8.1% and between fibers or batch to batch (n=3) (reproducibility) in the range 
      of 7.2-9.1%. The developed method was successfully applied to real water samples 
      while the relative recovery percentages obtained for the spiked water samples at 
      0.2 ng mL(-1) were from 84 to 107%.
