环境介质中锑形态分析技术的研究进展

Review on the analytical technique for antimony speciation in environmental media

评述了近几年不同环境介质中锑的形态分析方法,其中,电感耦合等离子体质谱法具有检出限低、灵敏度高、稳定性好、分析速度快等优点,在锑的形态分析领域受到越来越多的关注。在形态分析之前,从复杂基质中提取不同形态锑,并保持其价态的稳定性是关键,灵敏的检测技术与高效的样品前处理技术以及分离技术的融合,为解决这一问题提供了思路。近年来,联用技术已经广泛应用于大气、水体、土壤和沉积物等环境样品中锑形态的检测。最后,探讨了该领域面临的挑战并对其未来的发展方向进行了展望。

This study reviews the speciation analysis methods of antimony indifferent environmental media in recent years.Inductively-coupled plasma mass spectrometry is widely used in the antimony speciation analysis because of its advantages such as low detection limit,high sensitivity,and good stability.Before the speciation analysis,extracting different forms of antimony from a complex matrix and maintaining its valence stability are essential.This can be achieved by combining the sensitive detection technology,efficient sample pretreatment techniques,and separation methods.In recent years,the combined techniques have been widely used for the determination of antimony in various environmental samples.Moreover,the challenges in this field and the development prospect of antimony speciation analysis method are discussed.
