    Abstract: A method was optimized for determination of polycyclic aromatic hydrocarbons (PAHs) in atmospheric samples by liquid chromatography (HPLC). Compared to florisil column, silica gel column had better purification effect, which effectively removed the background interference for target analysis. Furthermore, higher recovery of low rings number PAHs were obtained by controlling the solvent volume in the solvent conversion process. The recoveries of 16 PAHs in the spiked standard solutions ranged from 53% to 128% (RSD -3, and the quantification limit were 0.32-1.16 ng·m-3 for the air samples collected at 100 L·min-1 sampling rate and 24 h sampling time. The results of several actual atmospheric samples confirmed the feasibility of this method.
