Determination Method for Polycyclic Aromatic Hydrocarbons in Water by SBSE-TTDU-GC
A fast method for determination of polycyclic aromatic hydrocarbons(PAHs) in water samples was established. The samples from the Kuenming Lake, Yuyuantan Lake and Zizhuyuan Lake of suburb of Beijing were analyzed directly by using stir bar sorptive extraction-thermal desorption system-gas chromatography (SBSE-TDU-GC). These 7 PAHs in water samples can be qualified and quantified rapidly and simultaneously by SBSE-TDU-GC with high sensitivity and good reproducibility. This methods correlation coefficients of 7 PAHs are ≥0.9926.The recoveries of 7 PAHs in water samples ranged from 91.46% to 108.82%, And the relative standard deviations (RSDs) ranged from 1.04% to 4.42%. The concentrations of PAHs in Beijing suburban lake waters was significantly in a high pollution level, especially was in the highest pollution level in the Zizhuyuan Lake. It is indicating that the PAHs pollution in lake water have been serious. Therefore, it is imperative to implement effective management of water pollution and strengthen the PAHs pollution control in lakes and surrounding water.
