TI  - Multiwalled carbon nanotubes as adsorbents of solid-phase extraction for 
      determination of polycyclic aromatic hydrocarbons in environmental waters coupled 
      with high-performance liquid chromatography.
PG  - 27-36
AB  - Multiwalled carbon nanotubes (MWCNTs) were used as a novel kind of solid-phase 
      extraction adsorbents in this work as well as an analytical method based on 
      MWCNTs solid-phase extraction (SPE) combined with high-performance liquid 
      chromatography (HPLC) was established for the determination of polycyclic 
      aromatic hydrocarbons (PAHs), some of which belong to typical persistent organic 
      pollutants (POPs) owing to their carcinogenicity and endocrine disrupting 
      activity. Several conditions that probably affected the extraction efficiency 
      including the eluent volume, sample flow rate, sample pH and the sample volume 
      were optimized in detail. The characteristic data of analytical performance were 
      determined to investigate the sensitivity and precision of the method, and the 
      method was applied to the determination of PAHs in environmental water samples 
      such as river water sample, tap water sample and wastewater sample from the 
      constructed wetland effluent. The experimental results indicated that there were 
      excellent linear relationship between peak area and the concentration of PAHs 
      over the range of 0.04-100 microg L(-1), and the precisions (RSD) were 1.7-4.8% 
      under the optimal conditions. The detection limits of proposed method for the 
      studied PAHs were 0.005-0.058 microg L(-1) (S/N=3). The recoveries of PAHs spiked 
      in environmental water samples ranged from 78.7 to 118.1%. It was concluded that 
      MWCNTs packed cartridge coupled with HPLC was an excellent alternative for the 
      routine analysis of PAHs at trace level.
