Determination of tetrabromobisphenol A and bisphenol A in environmental water using carboxylated multiwalled carbon nanotubes as sorbent for solid-phase extraction combined with liquid chromatography-tandem mass spectrometry
摘要
Abstract
A method for the determination of tetrabromobisphenol A and bisphenol A in environ-mental water using carboxyl-functionalized multiwalled carbon nanotubes as solid-phase extraction sorbent and liquid chromatography-tandem mass spectrometry was established. Com-parison of three nanomaterials including multiwalled carbon nanotubes,C60 and carboxyl-func-tionalized multiwalled carbon nanotubes used as solid-phase extraction sorbents was made. After preconcentration by solid-phase extraction,tetrabromobisphenol A and bisphenol A were separa-ted on a Thermo Scientific Hypersil C18 column(150 mm×4. 6 mm,3 μm)and then detected by tandem mass spectrometry in negative electrospray ionization(ESI)mode. The results showed a good linear response in the concentration range of 0. 02-1. 0 mg / L for tetrabromobisphenol A and bisphenol A,and the limits of detection(S / N = 3)were 0. 04 μg / L and 0. 2 μg / L for tetrabromo-bisphenol A and bisphenol A,respectively. The application of the proposed approach has been carried out for the determination of tetrabromobisphenol A and bisphenol A in spiked lake water and sea water samples. The recoveries varied from 82% to 99% with the relative standard devia-tions below 5. 0%. The proposed method can be used for the determination of tetrabromobisphe-nol A and bisphenol A at trace level in complex environmental samples.关键词
