AB  - In this study, graphene grown on stainless steel mesh efficiently incorporates 
      the advanced properties of graphene in the form of an ultra-thin coating with the 
      open geometry of the substrate, resulting in a highly sensitive and fast sorptive 
      device capable of extracting target analytes directly from sample matrices. The 
      synthesis of graphene on the stainless steel mesh was confirmed by scanning 
      electron microscopy (SEM) and transmission electron microscopy (TEM). The 
      advantages of the new microextraction device have been investigated for the 
      determination of polycyclic aromatic hydrocarbons (PAHs) in environmental water 
      samples in combination with gas chromatography-flame ionization detector 
      (GC-FID). The factors affecting the extraction efficiency such as stirring speed, 
      extraction time, ionic strength and desorption conditions, were investigated and 
      the optimal extraction conditions were established. Under the optimal extraction 
      condition, linearity was in the range of 0.003-100 ng mL(-1) with a correlation 
      coefficient of 0.9923-0.9985. The limits of detection (LODs) of the developed 
      method are obtained between 1 and 3 pg mL(-1). The repeatability was assessed at 
      two concentration levels (0.01 and 10 ng mL(-1)) and the relative standard 
      deviations (RSDs) obtained were 4.9-8.7%. The preparation reproducibility of 
      sorbent device, evaluated with the RSDs, was in the range of 7.3-10.2% (n = 5) in 
      one batch, and 8.3-11.0% (n = 5) among different batches. Finally, the proposed 
      method is applied for the determination of the target PAHs in the real water 
      samples.
