AB  - In this study, a wall-jet flow cell with a GRC (graphite reinforced by carbon) 
      electrode was designed for the amperometric detection of phenol and chlorophenols 
      in liquid chromatography. The voltammetric responses of these analytes at the GRC 
      electrodes are very similar to those at conventional glassy carbon electrodes. As 
      the GRC electrodes were made of the same materials as commercially available 
      mechanical pencil leads, they exhibit the advantages of low cost, simple surface 
      renewability, lower residual current, and good electrode-to-electrode 
      reproducibility, and thus can be used as disposable-type electrodes. 
      Chromatographic separations of phenol, o-chlorophenol (o-CP), 2,4-dichlorophenol 
      (2,4-DCP), 2,4,6-trichlorophenol (2,4,6-TCP), and pentachlorophenol (PCP) were 
      achieved with an ODS column using a mobile phase containing a mixture of CH3CN 
      and H20 (40:60) containing 25 mM L-(+)tartaric acid (pH = 4.5). Amperometric 
      detections were based on the electrochemical oxidation of these compounds around 
      +0.9 V vs. Ag/AgCl. Under the optimized conditions, linear calibrations were 
      obtained in a range up to 100 microM for phenol, o-CP, 2,4-DCP, 2,4,6-TCP, and 
      200 microM for PCP, with the correlation coefficients r2 of 0.9992, 0.9997, 
      0.9986, 0.9992, and 0.9968, respectively. The chromatographic detection limits 
      for the tested analytes were obtained at pmol levels.
