Considerable analytical methods have been developed for arsenic speciation in the last 5 years, the details of these new arsenic speciation procedures are thus summarized in present mini review. The performances of various sample pretreatment techniques including solid phase extraction, liquid-liquid extraction, hydride generation, liquid chromatography and capillary electrophoresis, which offer effective preconcentration/separation and eventually contribute greatly to excellent sensitivity and selectivity in arsenic speciation when coupling with suitable detection mode, are discussed and compared thoroughly. High-performance liquid chromatography coupling with inductively coupled plasma mass spectrometry and hydride generation atomic spectrometry are proved to be the most powerful hyphenated methodologies for arsenic speciation in environmental and biological matrices.
在过去五年中，已经开发出了大量用于砷形态分析的方法，因此在本小型综述中总结了这些新的砷形态分析程序的细节。本文全面讨论并比较了各种样品预处理技术的性能，包括固相萃取、液液萃取、氢化物发生、液相色谱和毛细管电泳，这些技术提供了有效的预富集/分离，并且在与合适的检测模式结合时，最终对砷形态分析的出色灵敏度和选择性有很大贡献。高效液相色谱与电感耦合等离子体质谱联用以及氢化物发生原子光谱法被证明是用于环境和生物基质中砷形态分析的最强大的联用方法。
