Abstract:

A homemade solidphase microextraction coating was used to determine polycyclic aromatic hydrocarbons (PAHs) and phthalate esters(PAEs)
 in water via headspace solidphase microextraction combined with gas chromatography（HSSPMEGC）. The conditions effecting on SPME were optimized as an extraction temperature of 70 ℃, an extraction time of 50 min by headspace, a desorption time of 5 min at 280 ℃, a NaCl concentration of 4 g and stirring rate in some speed. The detection limits were 0.005—0.1 μg/L, and the linear range was 1—100 μg/L. The recovery of east lake water in Wuhan City was 72.0%—116.3%, and the relative standard deviation (RSD) was 5.2%—8.5%.
