AB  - In this work, a novel nanoscale graphitic carbon nitride hybridized with copper 
      oxide (nano-g-C(3)N(4)/CuO) composite was prepared and used as the coating of 
      solid-phase microextraction (SPME) for the first time. The coating was applied to 
      adsorption and preconcentration of polycyclic aromatic hydrocarbons (PAHs) 
      including naphthalene, acenaphthene, fluorene, phenanthrene, anthracene, and 
      pyrene from water and soil prior to gas chromatography (GC) analysis. Compared 
      with pristine nanoscale graphitic carbon nitride (nano-g-C(3)N(4)) or copper 
      oxide (CuO), the as-prepared nano-g-C(3)N(4)/CuO composite as the coating of SPME 
      provided the best adsorption affinity for PAHs. Moreover, the extraction 
      efficiencies of the nano-g-C(3)N(4)/CuO coated fibers were much higher than that 
      of bulk-g-C(3)N(4)/CuO hybrids. The developed method exhibited excellent 
      linearity for target analytes in the range of 0.1-1000 ng/mL with determination 
      coefficient (R(2)) not lower than 0.9944. The limits of detection (LODs) of the 
      established method for the analysis of PAHs were achieved between 0.025 and 
      0.40 ng/mL. The relative standard deviations (RSDs) for three replicate 
      extractions with one fiber were determined from 2.5% to 7.3%. The fiber-to-fiber 
      reproducibility (n = 3) was 5.4-12.8%. The prepared coating also demonstrated 
      excellent thermal and chemical stability. The method was successfully applied to 
      analysis of target analytes in water and soil samples and the corresponding 
      contents were calculated between 0.07 and 1.58 mug/g.
