Determination of Organophosphorus Flame Retardants in Surface Water by Solid Phase Extraction Coupled with Gas Chromatography-Mass Spectrometry
摘要
Abstract
Organophosphorus flame retardants ( OPFRs), as their increasing production and consumption, are almost ubiquitous in environmental compartments. In this study, a solid phase extraction (SPE) coupled with gas chromatography-mass spectrometric (SPE-GC-MS) method was developed for the determination of 8 typical OPFRs. The targets in water samples were concentrated by Poly-Sery PSD SPE cartridge, and then eluted by 4 mL ethyl acetate. The OPFRs were qualified and quantified by GC-MS in selective ion scan monitoring method (SIM). Good linearity was observed in the range of 2 to 200 ng/L OPFRs with correlation coefficients varing between 0. 9937 and 0. 9995. The limits of detection and limits of quantification ranged from 0. 006 to 0. 850 ng/L and 0. 015 to 2.000 ng/L, respectively. Spiked recoveries of pure water and river water samples ranged from 70. 3% to 114. 3%, with the relative standard deviations less than 15%, except for tri(2-ethylhexyl) phosphate(TEHP). The satisfied recovery of TEHP was achieved when the spiked concentration was less than 50 ng/L. The results showed that the SPE-GOMS analytical method established was sensitive and accurate for the determination of OPFRs in surface water samples. Then the method was applied to analyze OPFRs in the water collected in Meiliang Bay of Taihu Lake, and it was found that the total concentration of OPFRs was ranging from 1000 to 2700 ng/L.关键词
