先前开发的现场铝形态分析方法用于研究在不同处理系统中使用铝凝固法在饮用水中发现铝的水平和状态。该方法通过分别测量可酸浸的比例和可萃取的比例来表征颗粒物和溶液中的铝。它能够沿着处理顺序确定水中铝的性质，有助于了解成品水中铝残留水平的来源。本文描述了获得的主要结果，尤其是检测到的处理问题。包括6个参考文献、图表。

A previously developed field aluminum speciation method was used to study at what level and in what state aluminum is found in drinking water at different treatment systems using aluminum coagulation. This method constitutes a characterization of the aluminum in particulate matter and in solution by measuring respectively what proportion is acid leachable and what proportion is extractable. Its capability to define the nature of the aluminum in water along a treatment sequence can help in understanding the origin of aluminum residual levels in finished water. This paper describes the main results obtained and more particularly the treatment problems detected. Includes 6 references, figures.
