Application of Polyacrylate in Determination of Organic Compoundsin Urban Wastewater by SPME-GC-MS

Under the optimized condition, the aromatic hydrocarbons benzene, toluene, ethylbenzene, xylene (BTEXs) and the polycyclic aromatic hydrocarbons (PAHs) in urban waste water were analyzed by headspace solid phase microextraction(HS-SPME)-GC-MS with polyacrylate coating. The fiber detection limits BTEXs and PAHs in aqueous sample are 0.6 ng/mL and 12 pg/mL respectively, the precision ranged from 1.9% to 5.5% and 2.0% to 9.8% (n=6) respectively.
