  • 摘要: 本研究利用酵母菌还原氯金酸得到纳米金,经过高温煅烧形成碳骨架支撑的金表面增强拉曼活性基底.以疏水性的多溴联苯醚(PBDEs)作为目标污染物,研究讨论了该基底的灵敏性与均一性.结果表明,基于基底表面碳与BDE-47之间的吸附作用,可以实现BDE-47的痕量检测,检测限为5×10-8 mol·L-1,并且BDE-47特征峰强度与浓度具有良好的线性关系,表明本方法可用于对BDE-47的定性定量分析,本方法对芴、芘等典型疏水污染物也具有较好的检测效果.
    Abstract: In this study,Au precursor was obtained by reduciton of chloroauric acid using yeast. The precursor was then suffered from high temperature calcination to form Au substrate supported on carbon skeleton. Hydrophobic polybrominated diphenyl ethers (PBDEs) were applied as the target pollutants to investigate the sensitivity and uniformity of the prepared substrate. The results indicated that the substrate could be used to detect trace BDE-47 due to the adsorption between PBDEs and carbon. The detection limit was 5×10-8 mol·L-1. The intensity of characteristic peak was linearly correlated with BDE-47 concentration. This method could be applied as a rapid analytical platform for PBDEs identification and quantification. In addition, the experiment results indicated that this method can be applied to analyze typical hydrophobic pollutants such as fluorene and pyrene.
