GC/GC-MS-analysis of polycyclic aromatic hydrocarbons (PAHs) in complex samples requires a previous treatment of the samples. In order to establish the effects of sorbents/solvents on the overall accuracy of the method, dispersive solid phase extraction as a method for the sample preparation in PAHs determination is employed using three different solvent mixtures and sorbents (PSA, C18 and PS-DVB). Recovery values are dependent on compound and sorbents. The highest mean recovery was recorded for cyclohexane/acetone-C18 combination (58.45%) which is satisfactory, with the values above 70% for naphthalene (76.05%), fluoranthene (80.22%), pyrene (111.99%) and benzo[g,h,i]perylene (71.77%). Similar recoveries were obtained for cyclohexane/acetone-PS-DVB (55.50%) and cyclohexane/acetone- PSA (55.30%). Cyclohexane/acetone gave the highest recovery values for all three sorbents, so this solvent mixture could be used in PAH extraction from various matrices. Though the obtained recovery values for the investigated sorbent/solvent combinations were not impressive, they might be a good basis for future researches since, as far as we know, PS-DVB was not used in dSPE sample preparation for GC/GC-MS analysis of PAHs. |
