摘要：

The determination of aluminum in water samples is performed with capillary electrophoresis after a convenient preconcentration procedure involving simple evaporation and subsequent filtration. By using a fluorescence detector, a detection limit lower than 20 μg/L aluminum is readily obtained. Only one peak from the aluminum-lumogallion complex is observed, which indicates the elimination of interference from foreign ions and lumogallion.
