硒的毒性和营养功能不仅与其总量有关 ,而且与其存在的化学形态有关。因此 ,硒的形态分析对于了解不同形态的硒化物在生物体和环境中的迁移转化规律具有重要意义。综述了硒化合物的不同形态的分析方法和技术 The toxic and nutritional functions of selenium are not only related to its total amount, but also to the chemical forms of its existence. Therefore, the speciation analysis of selenium is of great significance for understanding the migration and transformation rules of different forms of selenides in organisms and environments. The analytical methods and techniques of different forms of selenium compounds are reviewed
