摘　　要：铀是核工业活动中必不可少的原料之一。它的大量使用引起了人们对铀造成的人类健康和环境污染问题的担忧。鉴于铀在环境中常常以铀酰(VI)离子的形式存在,为了获得铀酰引起的环境污染和核事故污染的相关信息,需要建立对铀酰离子的快速识别与定量分析技术。作为一种能够同时提供铀酰离子含量和结构信息的分析技术,表面增强拉曼散射(Surface-enhanced Raman scattering, SERS)在铀酰离子的快速、高灵敏痕量分析上得到广泛关注与研究。本文总结了SERS技术在铀酰检测方面的研究进展,按照SERS基底类型来分类介绍了各类基底的优缺点,考察了SERS技术检测痕量铀酰离子的可行性。总体而言,SERS技术作为一种新兴的分析技术,在痕量检测、便携性及现场快速检测等方面极具优势,在铀酰离子检测领域的应用前景十分广阔。Uranium is an essential material in nuclear industry.However,its use raises concerns about the serious damage to human health and the natural environment problem caused by uranium.Therefore,in order to obtain the relevant information of uranyl⁃induced environmental pollution and nuclear accident pollution,it is necessary to establish a rapid identification and quantitative analysis technology for uranyl.Surface⁃enhanced Raman scattering(SERS)has been widely used in the rapid,sensitive and low⁃cost trace analysis of uranyl ions as an analytical method with the advantages of providing both the content and structure information of uranyl ions.In this paper,the research progress of SERS technology on the detection of uranyl is summarized,and the advantages and disadvantages of various substrates are introduced according to the types of SERS substrates.The feasibility of SERS technology for the determination of trace uranyl ions is investigated.As a new analytical technology,SERS technology has great advantages in trace detection,portability and on⁃site rapid detection,hence it has a broad application prospect in the field of uranyl ion detection.
