英文摘要The enrichment of polycyclic aromatic hydrocarbons (PAHs) in water samples with magnesium oxide (MgO) microspheres was evaluated, and four 3-5-ring PAHs were used as probes to validate the adsorption capacity of the material. Factors affecting the recovery of PAHs were investigated in detail. including the type and concentration of organic modifiers. elution solvents. particle size of the adsorbent, volume and flow rate of the samples, and the lifetime of MgO cartridges. The recoveries of four PAHs extracted from 20 mL of seawater spiked with standard PAHs ranged from 85.8% to 102 0% under the optimised conditions. The limits of detection varied from 1 83 ng L(-1) to 16.03 ng L(-1), indicating that the analytical method was highly sensitive Additionally, the proposed method was successfully used to enrich PAHs in seawater. Compared to conventional methods, the proposed method consumed less organic modifier (5% acetone). and cheaper sorbents with comparable extraction efficiency were employed (C) 2010 Elsevier B.V All rights reserved
