Abstract
The compound 2-hydroxy-1-carbazole carboxylate (HCC-) exhibits a shift in its fluorescence spectrum upon binding to aluminum in aqueous solu tion. Fluorescence studies at a variety of solution pHs and aluminum c oncentrations have been used to determine the most probable species in solution and binding constants of the complexes formed. The fluoresce nt chelating agent described in this paper can be used for the rapid d etermination of unperturbed free aluminum in aqueous solution.
