Polycyclic aromatic hydrocarbons (PAHs) are generated primarily during the incomplete combustion of organic matter and are ubiquitous environmental pollutants. For the first time, in this study, a mesoporous carbon derived from asphalt with high surface area (2300 m²g⁻¹ with an average of 1.2 cm³ g⁻¹) was utilized as a sorbent for the solid-phase extraction (SPE) of several PAHs in tap water samples. The factors influencing the extraction capability of the new material were investigated and the optimum conditions were determined to be as follows: Sample volume - 200 mL, no adjustment of sample pH, and sorbent amount - 50 mg. Under the most favorable SPE conditions, with gas chromatography-mass spectrometric analysis, the method exhibited a linear range of 0.5-50 μgL⁻¹ with limits of detection between 0.004 and 0.026 μgL⁻¹. The recoveries obtained from spiked tap water samples spiked at 1 μgL⁻¹ and 5 μgL⁻¹, were in the range 86.7-98.2% with relative standard deviations of <9%. The method was also applied to tap water samples collected from the local environment. The concentrations of PAHs detected ranged between 0.13 and 48 μgL⁻¹. The reusability of the sorbent was tested with five consecutive SPE extraction, and no carryover of analytes was observed.

多环芳烃（PAHs）主要在有机物不完全燃烧过程中产生，是普遍存在的环境污染物。在本研究中，首次将源自沥青的具有高表面积（2300 m²g ^-1，平均为 1.2 cm³ g ^-1）的介孔碳用作吸附剂，用于固相萃取 (SPE)自来水样品中的多环芳烃。研究了影响新材料提取能力的因素，确定了最佳条件如下：样品体积 - 200 mL，样品 pH 值未调整，吸附剂用量 - 50 mg。在最有利的SPE条件下，通过气相色谱-质谱分析，该方法的线性范围为0.5-50 μgL ^-1检测限在 0.004 和 0.026 μgL ^{-1 之间}。从以1 μgL ^-1和5 μgL ^-1加标的加标自来水样品获得的回收率在86.7-98.2% 的范围内，相对标准偏差<9%。该方法还应用于从当地环境中采集的自来水样品。检测到的多环芳烃浓度介于 0.13 和 48 μgL ^{-1 之间}。通过连续五次 SPE 萃取测试了吸附剂的可重复使用性，没有观察到分析物的残留。
