Abstract

Background

Selenium is an essential trace element that exists in various forms, including methylated species, each with distinct biological activities and toxicity profiles. Understanding these transformations is critical for evaluating selenium's role in health and the environment. This review was conducted through a targeted search of multiple databases, including PubMed, Scopus, Web of Science, and Google Scholar. Keywords such as "selenium methylation detection" and "analytical methods for selenium" were used to gather a broad and relevant selection of articles. Studies were included based on their relevance, methodological quality, and contributions to the field.

Results

The review provides a detailed analysis of both established and emerging analytical techniques for selenium detection. This includes gas chromatography-mass spectrometry (GC–MS), liquid chromatography-mass spectrometry (LC-MS), high-performance liquid chromatography (HPLC), X-ray absorption spectroscopy (XAS), and nuclear magnetic resonance (NMR). It evaluates the effectiveness of these methods in separating, identifying, and quantifying selenium species, with a particular focus on sensitivity, selectivity, and throughput. Additionally, new technologies such as capillary electrophoresis coupled with inductively coupled plasma-mass spectrometry (CE-ICP-MS) and laser-induced breakdown spectroscopy (LIBS) are discussed for their potential to enhance precision and efficiency.

Significance

This review highlights the critical role of advanced analytical methods in understanding selenium transformations and improving measurement accuracy. By addressing challenges such as matrix effects, overlapping retention times, and spectral interferences, the review underscores the importance of reliable selenium analysis for health and environmental assessments, and provides insights into the ongoing advancements in analytical technology.

期刊介绍： Chinese Journal of Analytical Chemistry(CJAC) is an academic journal of analytical chemistry established in 1972 and sponsored by the Chinese Chemical Society and Changchun Institute of Applied Chemistry, Chinese Academy of Sciences. Its objectives are to report the original scientific research achievements and review the recent development of analytical chemistry in all areas. The journal sets up 5 columns including Research Papers, Research Notes, Experimental Technique and Instrument, Review and Progress and Summary Accounts. The journal published monthly in Chinese language. A detailed abstract, keywords and the titles of figures and tables are provided in English, except column of Summary Accounts. Prof. Wang Erkang, an outstanding analytical chemist, academician of Chinese Academy of Sciences & Third World Academy of Sciences, holds the post of the Editor-in-chief.
