硒的形态分析方法综述

Review of Analytical Methods for Selenium Speciation

硒是人和动物必需的微量元素之一,硒过量或缺乏都会影响健康。不同硒形态的生物学功能及其代谢规律不同,所以开展硒形态分析研究至关重要。元素形态分析是对被分析物中实际存在的化学形式进行识别和定量。本文从硒形态分析所涉及的样品提取、分离和定量等方面开展论述,探讨了不同色谱分离方法和ICP-MS定量方法在硒形态分析中的应用进展,提出了硒形态分析研究的发展方向与前景。

Selenium is one of the essential trace elements for humans and animals.Excessive or lack of selenium will affect health and cause diseases.Different selenium forms have different biological functions and their metabolic laws,so it is very important to carry out research on selenium forms.Element speciation analysis is to identify and quantify the chemical forms that actually exist in the analyte.Sample extraction,separation and quantification involved in selenium speciation analysis were discussed.The application progress of different chromatographic separation methods and ICP-MS quantitative methods in selenium speciation analysis was discussed,and the development direction and prospects of the study of selenium speciation analysis were put forward.
