Cr（III）和Cr（VI）物种之间的毒性差异是最近开发用于区分它们的分析方法的主要原因之一。非色谱方法为此提供了非常方便的工具，可以作为色谱方法的快速和廉价的替代品。本文综述并讨论了共沉淀法、透析法、溶剂萃取法和固相萃取法等非色谱法测定天然水样中铬的方法。本调查将试图涵盖2005年至2010年的最新技术水平。
The difference in toxicity between Cr(III) and Cr(VI) species is one of the main reasons for the recent developments in analytical procedures for their differentiate. Non-chromatographic methods offer highly convenient tools for this purpose and can be used as a fast and cheap alternative to the chromatographic processes. The present work overviews and discuss different non-chromatographic procedures for speciation of chromium in natural water samples such as coprecipitation, dialysis, solvent and solid phase extraction. This survey will attempt to cover the state of-the art from 2005 to 2010.
