Because of its toxic effects on living beings, Al may represent an environmental hazard, particularly under increased acidic conditions. Growing environmental concern over the presence of increased Al concentrations in soil solutions and fresh waters resulted in the development of numerous analytical techniques for the determination of Al species. Al has a very complex chemistry that is significantly influenced by pH. Different Al species are present in environmental solutions, and many of them are unstable. Contamination of samples and reagents by extraneous Al represents an additional problem in speciation of Al at trace concentrations. Due to these reasons quantitative determination of particular chemical forms of Al is still a very difficult task for analytical chemists. The most important analytical methodologies of the last decade and new trends for the speciation of Al in environmental samples are comprehensively reviewed here.
由于铝对生物具有毒性作用，它可能会造成环境危害，尤其是在酸性增强的条件下。环境中对土壤溶液和淡水中铝浓度升高的关注度不断增加，促使人们开发了许多用于测定铝形态的分析技术。铝具有非常复杂的化学性质，受pH值影响很大。环境溶液中存在不同的铝形态，其中许多是不稳定的。在痕量浓度下，样品和试剂被外来铝污染是铝形态分析中的另一个问题。由于这些原因，对分析化学家来说，定量测定特定化学形态的铝仍然是一项非常艰巨的任务。本文全面综述了过去十年中最重要的分析方法以及环境样品中铝形态分析的新趋势。
