AB  - A novel solid-phase microextraction (SPME) fiber was fabricated by direct 
      electrodeposition of polyaniline (PANI) coated the titania nanotube arrays in 
      situ grown on the titanium wire followed by carbonization at 500 degrees C under nitrogen 
      atmosphere. The resulting titanium-based fiber with nitrogen-enriched 
      carbonaceous material coated titania nanotubes (N-C/TiO(2)NTs/Ti) showed better 
      extraction performance for ultraviolet (UV) filters among model aromatic 
      compounds compared with common PANI as well as commercial polydimethylsiloxane 
      and polyacrylate coatings. The influence of various experimental parameters on 
      the extraction efficiency of UV filters were investigated and optimized. The 
      calibration curves were linear from 0.2 to 200mugL(-1) for each analyte with 
      correlation coefficients above 0.9980. Limits of detection (LODs) and limits of 
      quantitation (LOQs) ranged from 0.03 to 0.05mugL(-1) and from 0.11 to 0.18mugL(-1) 
      for UV filters, respectively. Relative standard deviations (RSDs) for single 
      fiber repeatability ranged from 3.3% to 4.1% (n=5) and RSDs for fiber-to-fiber 
      reproducibility (n=3) varied from 5.7% to 7.7%. The proposed method was 
      successfully applied to the preconcentration and determination of target UV 
      filters in river water and wastewater samples with good recoveries from 86.2% to 
      113%. Moreover this novel Ti-based fiber is mechanically and chemically stable, 
      and can be easily prepared in a highly reproducible manner.
