摘　　要：综述了近5年来铬的形态分析的新进展。讨论了水样、沉积物和生物样品中铬形态分析的预处理方法,概括了当前常用的分离富集方法。介绍了电化学方法,分光光度法,原子光谱法等在铬的形态分析中的新应用,并展望了铬的形态分析的发展前景。The new progress about the speciation analysis of chromium in recent five years has been reviewed. The pre-disposal of samples for water,sediment and biology are discussed. The methods for separation and preconcentration for chromium speciation are recapitulated and the applications of electrochemical analysis,spectrophotometry and atomic spectrometry in the speciation analysis of chromium are introduced. The prospect about speciation analysis of chromium is also expected.
