In this study, marble powder was evaluated as a cheap, easy to prepare and efficient green sorbent for miniaturized solid phase extraction of polycyclic aromatic hydrocarbons (PAHs) and determination by high performance liquid chromatography with UV detection. Under the optimized experimental conditions, wide linear dynamic ranges were achieved in the range of 0.1–200 μg L−1, with correlation coefficient higher than 0.996. The limits of detection and quantification for target analytes could reach 16.3–120.2 and 54.3–398 ng L−1, respectively. The method precision based on obtained RSD values in the range of 4.9–7.9% (n = 8) was very satisfactory.
