摘要：
Accelerated solvent extraction with the use of a dichloromethane-acetone mixture (1: 1 ratio) was applied to extraction of six PAH. This method allowed the recovery ranging from 70 to 115% and good repeatability (SD = 1.9-5.7). In order to determination method, liquid chromatography with the fluorescence detector and gas chromatography-mass spectrometry were applied. The validation of the method for PAH extraction and determination in soil was necessary for the purposes of further certification tests aimed at determination the certified value of the new reference material and its homogeneity.
