This article includes a survey of chromium (Cr) occurrence in different environmental compartments, its pathways in the environment and the cross-sectional presentation of Cr speciation methods against the background of Cr chemistry. The aim of the article is to demonstrate that knowledge of interconversion processes between different Cr forms is necessary to understand its behaviour and role in the environment, in addition to enabling reliable Cr speciation analysis to be performed. The current methods of Cr speciation are presented, characterized and their usefulness discussed. These must rely on superior separation and detection capabilities since Cr in environmental compartments is mostly at trace or ultra-trace level. The need for using unique techniques of sampling, storage, handling and separation for Cr speciation is documented.
本文包括对不同环境介质中铬(Cr)的存在情况、其在环境中的迁移途径以及在铬化学背景下铬形态分析方法的横断面介绍。本文的目的是表明,了解不同铬形态之间的相互转化过程对于理解其在环境中的行为和作用是必要的,此外还能进行可靠的铬形态分析。文中介绍了当前的铬形态分析方法,对其进行了表征并讨论了其有用性。由于环境介质中的铬大多处于痕量或超痕量水平,这些方法必须依赖卓越的分离和检测能力。文中记录了铬形态分析在采样、储存、处理和分离方面使用独特技术的必要性。
