摘要
元素形态分析是定量测定样品中元素的一个或多个化学形态的过程,元素形态分析首先是对元素的形态进行有效分离,然后进行检测。固相萃取是有效的分离富集技术,在微量元素形态分析中获得了广泛的应用。文章介绍了固相萃取的基本原理和一般操作方法,综述了微量元素形态分析中的固相萃取分离技术,总结了固相萃取中常用的吸附剂,如键合硅胶、有机聚合物、纳米颗粒物质和生物材料,在样品前处理中的应用。对固相萃取技术的优缺点进行了评述,对其在微量元素形态分析中的发展趋势进行了展望。
Element speciation analysis is the analytical activity of identifying and/or measuring the quantities of one or more individual chemical species in a sample. The specific forms of an element were separated effectively first from a given matrix before determination. Solid phase extraction（ SPE） is a technique designed for rapid,effective and selective sample preparation and purification prior to analysis,and was widely used in speciation analysis of trace elements.In this paper,the basic principle and procedure of SPE were introduced,applications of SPE in speciation analysis of trace elements were reviewed,and the sorbent materials for SPE were summarized. The trend and prospect of SPE application in speciation analysis were proposed.
