AB  - Uniform and dense ZnO nanosheets (ZnONSs) as a solid-phase microextraction (SPME) 
      fiber coating were fabricated on the surface of nickel and titanium oxide 
      composite nanosheets (NiO/TiO(2)CNSs) which were in situ grown on the Nitinol 
      (NiTi) wire in a hydrothermal procedure. The SEM micrographs illustrate that 
      ZnONSs with the average thickness of 50 nm have been electrochemically grown on 
      the NiTi fibers. The interconnected ZnONSs coating presents a porous 
      nanostructure with large surface area. The as-fabricated fiber exhibits high 
      extraction capability and excellent extraction selectivity for ultraviolet (UV) 
      filters among the selected aromatic compounds. The main parameters affecting 
      extraction performance were examined and optimized. Under the optimized 
      conditions, the calibration curves were linear from 0.05 to 500 ng mL(-1) with 
      correlation coefficients above 0.999. The limits of detection (S/N = 3) ranged 
      from 0.011 to 0.042 ng mL(-1), while the limits of quanitification (S/N = 10) 
      were in the range of 0.037-0.14 ng mL(-1). Relative standard deviations (RSDs) 
      for the single fiber repeatability were less than 7.4% (n = 5) and RSDs for the 
      fiber-to-fiber reproducibility were below 8.2% (n = 5). The proposed method was 
      successfully applied to the proconcentraction and determination of trace UV 
      filters in real water samples. Moreover, the ZnONSs coating can be fabricated in 
      highly reproducible manner with long durability.
