分子荧光光谱在原油分析中的应用概述

摘要

Molecular fluorescence spectroscopy is sensitive to the aromatic hydrocarbons components whose content is high in crude oil,thus it is an effective way for qualitative and quantitative analysis of crude oil.It has the advantages of rapid,high sensitivity,simplicity of operation,and so on.Herein,we review the application of molecular fluorescence spectroscopy in crude oil analysis according to different analytical modes,such as routine,synchronous and timeresolved fluorescence spectroscopy,and provide a prospective view on its development.%原油中富含各类芳烃,而分子荧光光谱对芳烃成分非常敏感,因此它是原油定量及定性分析的常用手段,具有灵敏度高、检测限低、操作简单、分析速度快捷等优点。本文以不同荧光光谱分析模式进行分类,通过介绍常规分子荧光光谱、同步荧光、时间分辨荧光等分析手段,对分子荧光光谱在原油分析中的应用做一概述,并对其发展趋势做了展望。
