Dissolved organic aluminum species in the Seta Riverwater were examined using high-performance cation-exchange chromatography with fluorometric detection of the lumogallion-aluminum complex. The separation was carried out according to the chargeon the aluminum species. Dissolved organic aluminum species, as most of them wereexpected to have a charge of +1 or less, will produce the first peak ; however, this peakwas small all year. Analytical conditions such as the reagent concentration or the use ofa disk filter in the case of sample injection, have little influence on the peak. Whenhumic substances, collected from the Seta River water using a hydrophobic resin DAX-8column, were added to the Seta River water, the peak was enhanced according to theamount of humic substances. We concluded that the dissolved organic aluminum complex,such as that with humic substances, scarcely existed in the Seta River water.
