Determination of PAHs and OPFRs in Atmospheric Particulate Matters by High Performance Solvent Extraction-Solid Phase Extraction/Gas Chromatography-Mass Spectrometry
Polycyclic aromatic hydrocarbons(PAHs) and organophosphorus flame retardants(OPFRs) are widespread and persistent organic pollutants in the environment.A high performance solvent extraction(HPSE)-solid phase extraction(SPE)/gas chromatography-mass spectrometry(GC-MS) was established for the determination of 16 PAHs and 15 OPFRs in atmospheric particulate matters.The extraction solvent of HPSE was ,n,-hexane-dichloromethane(1∶1,by volume) solution.Meanwhile,other instrument parameters of HPSE(e.g.temperature and pressure) were also optimized.The extracts were concentrated by rotary evaporation,and then purified by Florisil solid phase extraction column.The eluents for PAHs and OPFRs were 10 mL of ,n,-hexane-dichloromethane(1∶1) and 10 mL of ethyl acetate,respectively,and then the eluents were concentrated and determined by GC-MS.The linear ranges for 16 PAHs and 15 OPFRs were 0.001-2.0 μg/mL,and the correlation coefficients(,r,2,) were greater than 0.99.The limits of detection(LODs,,S,/,N ,= 3) for PAHs and OPFRs were 0.10-10.00 μg/L and 2.59-75.00 μg/L,respectively.The limits of quantitation(LOQs,,S,/,N ,= 10) were 0.33-33.33 μg/L and 8.63-250.00 μg/L,respectively.The average recoveries for 16 PAHs and 15 OPFRs were in the range of 73.0%-98.0% and 69.3%-111%,with their relative standard deviations(RSDs) of 3.7%-13% and 2.5%-17%,respectively.The results showed that this method was suitable for the determination of PAHs and OPFRs in atmospheric particulate matter samples.
