英文摘要 | 建立了羧基化碳纳米管固相萃取-液相色谱-串联质谱联用检测环境水体中四溴双酚A和双酚A的方法。比较了多壁碳纳米管、C60和羧基化多壁碳纳米管作为固相吸附剂对水体中四溴双酚A和双酚A的吸附效率。固相萃取浓缩后的样品经Thermo Scientific Hypersil C_(18)色谱柱(150 mm×4.6 mm,3μm)分离,采用串联质谱负离子模式进行检测。结果表明,四溴双酚A和双酚A在0.02~1.0 mg/L范围内具有良好的线性关系(r2≥0.99),空白样品中的检出限(S/N=3)分别为0.04μg/L和0.2μg/L。将所建立的方法应用于实际环境水体中四溴双酚A和双酚A的检测,添加回收率在82%~99%之间,精密度小于5.0%,该方法可用于复杂环境样品中痕量四溴双酚A和双酚A的检测。 |
中文摘要 | A method for the determination of tetrabromobisphenol A and bisphenol A in environmental water using carboxyl-functionalized multiwalled carbon nanotubes as solid-phase extraction sorbent and liquid chromatography-tandem mass spectrometry was established. Comparison of three nanomaterials including multiwalled carbon nanotubes, C60 and carboxyl-functionalized multiwalled carbon nanotubes used as solid-phase extraction sorbents was made. After preconcentration by solid-phase extraction, tetrabromobisphenol A and bisphenol A were separated on a Thermo Scientific Hypersil C_(18) column (150 mm*4.6 mm, 3 mum) 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 mug/L and 0.2 mug/L for tetrabromobisphenol 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 deviations below 5.0%. The proposed method can be used for the determination of tetrabromobisphenol A and bisphenol A at trace level in complex environmental samples. |
