摘要

辛基酚广泛应用于涂装、橡胶等多种行业，是典型的酚类内分泌干扰物(Phenolic Endocrine Disrupting

PEDs) 。环境介质中低浓度的辛基酚也可能造成很大的环境危害，亟待开发高效、快速的检测方法，预警和预报其环境风险。本文通过制备以银粒子为核，表面分子印迹聚合物为壳的银核辛基酚印迹微球，试验表面增强拉曼散射与分子印迹技术联用快速检测痕量辛基酚的方法。透射电镜(TEM)、X-衍射(XRD) 和元素能谱分析(Energy Dispersive Spectroscopy

EDS) 表征的结果表明：银核辛基酚印迹微球是银核外包裹二氧化硅的核壳结构，辛基酚印迹在壳层的表面，壳层不影响银核的晶型结构。壳层厚度影响银核辛基酚印迹微球选择性吸附辛基酚及银核表面拉曼光增强效果，最佳壳层厚度为25 nm。表面增强拉曼光谱与分子印迹技术联用检测辛基酚的最低检测限为10

Abstract

Octylphenol is widely used in coating

rubber and other industries. It is a typical Phenolic Endocrine Disruptors (PEDs) . Low concentration of octylphenol in environmental medium may also cause great environmental harm. It is urgent to develop efficient and rapid detection methods to warn and predict its environmental risks. In this study

microspheres were prepared with silver particles as core and octylphenol engram on surface. A method for rapid determination of trace octylphenol by surface enhanced Raman scattering and molecular engram was tested. The results of Tran

smission Electron Microscope (TEM)

X-ray diffraction (XRD) and elemental Energy Dispersive Spectroscopy (EDS) showed that the silver core octylphenol engram microspheres are the core-shell structure of silica wrapped with shell

octylphenol is imprinted on the surface of the shell

and the shell did not affect the crystal structure of the silver core. The shell thickness affects the selective adsorption of octylphenol and Raman light enhancement effect

the best shell thickness of microspheres is 25 nm. The minimum detection limit of octylphenol by surface enhanced Raman spectroscopy combined with molecular engram is 10
