• 摘要：采用PCV络合比色法和Ferron逐时络合比色法，选取3种典型环境中的水体为研究对象：江西德兴铜矿地区的乐安江、白洋淀地区以及从源水、自来水到铝锅煮沸水的序列水样，着重分析其中铝的含量及其形态分布，并讨论了铝的含量及其形态的变化对3种典型环境的影响。

• Abstract：Three kinds of water samples were selected to be analyzed for their concentrations and fractions of aluminum including samples collected from Le'an River in Jiangxi Province, Baiyangdian Lake, tap water and boiled water using aluminum pot. The fractionation of aluminum along Lean Rvier was remarkable affected by waste water discharged from Dexing Copper Mine. In Baiyangdian Lake, polymeric and complexed aluminum fractions were identified in some samples. Moreover, there was still some residual aluminum in tap water. After boiled with aluminum pot, not only the amount of total aluminum raised, but also the concentration and proportion of active monomeric aluminum fraction increased significantly.

• Key words：aluminum  fractionation  polycatechol violet  ferron  timed spectrophotometry  water  tap water.
