AB  - A conducting copolymer of pyrrole and phenol was electrochemically synthesized on 
      steel frits as a sorbent. The applicability of the frit was assessed for the 
      solid-phase extraction of trace amounts of polycyclic aromatic hydrocarbons 
      (PAHs) in aqueous samples followed by HPLC-UV. The coating produced was very 
      adherent and the scanning electron microscopy (SEM), energy-dispersive X-ray 
      spectroscopy (EDX) and FTIR spectrum for the coated frit were studied. The 
      effects of various parameters on the efficiency of the solid-phase extraction 
      process, such as the sample loading rate, elution solvent type, salt effect, 
      volume and flow rate of sample and elution solvent were investigated. Under the 
      optimal conditions, the calibration curves were obtained in the range of 
      0.1-500ngmL(-1) (r(2)>0.98) and the LODs (S/N=3) were obtained in the range of 
      0.01-0.08ngmL(-1). Relative standard deviations (RSDs) for intra- and inter-day 
      precision were 2.7-10.2% and 3.6-11.4%, respectively. The recoveries (8 and 
      40ngmL(-1)) ranged from 79% to 115%. The simplicity of experimental procedure, 
      short sample analysis, high extraction efficiency, and the use of low-cost 
      adsorbent show the potential of this method for routine analysis of PAHs in real 
      samples.
