  • 摘要: 以Ag@SiO2核壳粒子为基底，利用表面增强拉曼光谱（SERS）技术实现酚类内分泌干扰物的快速检测。采用柠檬酸钠还原硝酸银制得银纳米粒子，以正硅酸乙酯为硅源，在银纳米颗粒表面包裹不同厚度的SiO2得到Ag@SiO2核壳粒子。通过透射电镜、紫外光谱、X射线衍射等表征手段对Ag@SiO2核壳粒子进行了表征和分析。以辛基酚为探针研究Ag@SiO2粒子表面增强拉曼效应与SiO2厚度、核壳粒子浓度的关系及辛基酚的检测限，并以此法检测实际环境样品中辛基酚的含量。结果表明，辛基酚的表面增强拉曼效应随着Ag@SiO2壳厚的增加而减弱，随着辛基酚浓度的增大而增强，且在1 390 cm-1处的峰强信息与浓度有着良好的线性关系，辛基酚最低检测限浓度为1 μg·L-1，可以实现辛基酚的SERS检测。
    Abstract: Surface-enhanced Raman spectroscopy (SERS) was employed to achieve a rapid detection of phenolic endocrine disruptors using core-shell Ag@SiO2 nanoparticles as the substrate.In this study,Ag nanoparticles were prepared through the reduction of silver nitrate with sodium citrate.Core-shell Ag@SiO2 nanoparticles were then synthesized by packaging SiO2 parcels with different thicknesses using tetraethoxysilane as the silica source.Such techniques as transmission electron microscopy (TEM),UV-vis spectroscopy,and X-ray diffraction (XRD) were introduced to characterize and analyze Ag@SiO2 nanoparticles.In addition,the relationships between the surface-enhanced Raman effect of Ag@SiO2 particles and the SiO2 thickness as well as the core-shell particle concentration were investigated using octylphenol as a probe molecule.Moreover,the detection limit of octylphenol was also considered,and the octylphenol content in real environmental samples was determined using the established quantitative relationship.The results show that the surface-enhanced Raman effect of octylphenol gradually weakened with increasing Ag@SiO2 shell thickness but became stronger with increasing octylphenol concentration.Furthermore,the results show that the detection limit of octylphenol is 1 μg·L-1,and a good linear relationship between the peak area at 1 390 cm-1 and the octylphenol concentration was obtained.This study demonstrates that octylphenol can be rapidly detected by SERS.
