TI  - Selective and efficient solid-phase microextraction of polycyclic aromatic 
      hydrocarbons in water by robust two-dimensional zinc oxide nanosheets grown on a 
      superelastic nickel-titanium alloy fiber prior to determination by HPLC-UV.

AB  - Oriented zinc oxide nanosheets (ZnONSs) were directly grown on pretreated 
      nickel-titanium alloy (NiTi) fiber substrates without a traditional seeding layer 
      of ZnO by electrochemical deposition for the first time. The fiber coatings were 
      characterized by scanning electron microscopy and energy dispersive X-ray 
      spectrometry. Direct growth of ZnONSs on the NiTi fiber substrate was dependent 
      on the type of zinc salt. The adsorption performance of the ZnONSs coatings was 
      evaluated using representative aromatic compounds as model analytes together with 
      high performance liquid chromatography with ultraviolet detection. The 
      as-prepared fiber shows higher extraction capability for the selected polycyclic 
      aromatic hydrocarbons (PAHs) than for ultraviolet filters in water samples, and 
      better extraction selectivity for PAHs. For this purpose, the important 
      experimental parameters were optimized for the extraction of PAHs. Under the 
      optimized conditions, the calibration curves are linear in the range of 0.03-200 
      mug L-1 with correlation coefficients greater than 0.999. Limits of detection 
      ranged from 0.011 mug L-1 to 0.082 mug L-1. Intra-day and inter-day relative 
      standard deviations (RSDs) of the developed method with a single fiber ranged 
      from 2.69% to 4.18% and from 4.44% to 5.40%, respectively. RSDs for the 
      fiber-to-fiber reproducibility varied between 5.57% and 7.66%. The developed 
      method was successfully applied for selective preconcentration and determination 
      of trace PAHs in five real water samples. Relative recoveries varied from 84.5% 
      to 104% with RSDs between 1.65% and 8.30%. Furthermore, the as-prepared fiber is 
      highly stable.
