摘要
随着时代发展和仪器分析技术的进步,微量重金属元素As、Hg、Se等对健康的影响越来越受民众关注,在各种"超标事件"层出不穷的今天,元素形态分析技术的发展具有重要意义。联用技术集高效分离与高灵敏度检测技术于一体,是形态分析技术发展的必然趋势。本文围绕As、Hg、Se元素的形态分析对现代常用的仪器联用技术及相应的样品预处理技术进行综述,并讨论各种方法的优缺点和未来元素形态分析的发展前景,为研究者检测元素形态方法的选择提供参考。
With time going on and instrumental analytical techniques progressing, the health effects of common trace elements （for example As, Hg and Se） have gained more attention. As an increasing number of ‘exceeding standard＇ incidents occur, the development of analytical techniques for element speciation studies is of great significance. Hyphenated analytical techniques enabling highly efficient separation and highly sensitive detection are the inevitable trend of element speciation analysis. The aim of this article is to review modern hyphenated instrumental techniques with sample pretreatment procedures for element speciation analysis. The advantages and disadvantages of various analytical techniques and the future prospects of element speciation analysis are also discussed aiming to provide sufficient references for the choice of analytical methods for element speciation analysis.
