天然水体铀的形态分析研究进展

Research Progress on Analysis Method of Uranium Speciation in Natural Water

天然水体中铀的形态分析是铀的环境评价研究的重要内容之一。本文综述了铀在天然水体中的主要存在形态,按照分析方法的特点,将形态分析划分为理论计算法和分析测定法,较为详细地介绍了X射线吸收精细结构光谱(XAFS)、X射线光电子能谱(XPS)、荧光时间衰减光谱(TRLFS)等分析方法,并阐述了铀的形态分析研究现状及下一步展望。通过本文综述,可以为天然水体中铀的形态分析研究提供参考。

The study on uranium speciation in natural water is one the important contents of uranium environmental assessment. The main speciation of uranium in natural water were reviewed,the analysis methods of uranium speciation in natural water were mainly discussed. X-ray absorption fine structure spectroscopy（ XAFS）,X-ray photoelectron spectroscopy（ XPS） time resolved laser fluorescence spectroscopy（ TRLFS） and other methods were summarized in detail. The research status of uranium speciation and the next steps of the research were described. The contents were helpful for researchers to carry out research works about the speciation analysis of uranium in natural water.
