      morphological, compositional, and size-depended control of bimetallic oxide 
      nanostructures grown on nickel-titanium alloy substrates.

AB  - Nickel-titanium oxide nanotubes (NiTiONTs), nanoparticles, and nanopores were in 
      situ grown on NiTi fiber substrates by controlling anodization parameters. The 
      adsorption performance of different bimetallic oxide nanostructures was evaluated 
      using typical aromatic compounds including chlorophenols, phthalic acid esters, 
      ultraviolet filters (UVFs), and polycyclic aromatic hydrocarbons (PAHs) coupled 
      to HPLC-UV. The results clearly indicate that these NiTiO nanostructures show 
      good extraction capability for UVFs and PAHs. The extraction performance of UVFs 
      and PAHs greatly depends on the surface morphologies and sizes of the grown NiTiO 
      nanostructures along with their elemental compositions. Compared with NiTiO 
      nanoparticle and nanopore coatings, the longer well-aligned NiTiONT coating 
      exhibits better extraction capability and selectivity for PAHs than for UVFs. 
      Therefore, the extraction parameters of the NiTi@NiTiONT fiber for PAHs were 
      investigated and optimized. Under optimized conditions, the proposed method was 
      linear in the range 0.05-200 mug L(-1) with correlation coefficients above 0.999. 
      Limits of detection were between 0.008 and 0.124 mug L(-1). Relative standard 
      deviations (RSDs) of the intra-day and the inter-day analyses with the single 
      fiber varied from 4.09 to 6.33%. RSDs for fiber-to-fiber reproducibility of the 
      proposed method with five fibers prepared in different batches were between 5.75 
      and 7.43%. The applicability of the proposed method was investigated by the 
      enrichment and determination of target PAHs in environmental water samples and 
      relative recoveries of 84.5 +/- 6.5 - 116 +/- 7.8% were achieved. Notably, the 
      prepared fiber was stable up to 250 times. Graphical abstract.
