表面增强拉曼光谱在偶氮染料检测中的研究进展

摘要

Status of azo dyes detection was described briefly. The methods of surface enhanced Raman spectroscopy in the detection of azo dyes were reviewed. The application of three kinds of enhanced substrates such as metal sol, metal electrode and metal film in the detection of azo dyes was introduced. Trend of its development of in the detection of azo dyes was also prospected. Surface enhanced Raman spectroscopy is a new spectral analysis technique. It has the advantages of simple operation, rapid and high sensitivity, and it opens a new way for the detection of azo dyes.%简述了偶氮染料的检测现状,对偶氮染料研究中表面增强拉曼光谱检测方法进行了综述.介绍了表面增强拉曼光谱用金属溶胶、金属电极、金属薄膜3种增强基底在偶氮染料检测中的方向,并对其在偶氮染料检测中的研究前景进行了展望.表面增强拉曼光谱法是一种新型光谱分析技术,具有操作简单、快速、灵敏度高等优势,为偶氮染料的检测开辟了新道路.
