Determination of Polycyclic Aromatic Hydrocarbons in Environmen-tal Water by HPLC with Stir Bar Adsorption Extraction Based on Co-valent Organic Framework Coating
摘要
Abstract
1,3,5-Tri(4-aminophenyl)benzene(TPB)and 2,5-divinyl-1,4-phenyldiformalde-hyde(DVA)were adopted as monomers to prepare a homogeneous covalent organic framework(TPB-DVA-COF)coated stir bar.The stir bar combined with high performance liquid chromatography was used for the extraction and detection of six polycyclic aromatic hydrocarbons(PAHs)in environmental water samples.Scanning electron microscopy(SEM),transmission electron microscopy(TEM),Fourier transform infrared spectroscopy(FTIR)were performed to characterize the material to confirm successful preparation of TPB-DVA-COF.Meanwhile,a series of experimental parameters includ-ing ion strength,extraction temperature,stirring rate,extraction time and desorption time were op-timized.Under the optimized conditions,there were good linear relationships for phenanthrene(Phe),fluoranthene(Fla)and pyrene(Pyr)in the range of 0.20-200 μg/L,chrysene(Chr),ben-zofluoranthrene(B[b]f)and benzopyren(B[a]p)in the range of 0.05-200 μg/L,with the correla-tion coefficients(r)not less than 0.998 5,and enrichment factor could be reached 225 folds.The limits of detection(LODs,S/N=3)were in the range of 0.007-0.150 μg/L,and the relative stan-dard deviations(RSDs)were in the range of 3.8%-6.1%for one bar(n=5),respectively.In the case of real samples analyses,the spiked recoveries were 87.1%-104%.The results showed that the de-veloped method could be successfully applied to the accurate and highly sensitive detection of PAHs in actual environmental water samples.关键词
