✦ Synopsis

The compound 2-hydroxy-l-carbazole carboxylate (HCC-) exhibits a shift in its fluorescence spectrum upon binding to ahunin~ in aqueous solution. Fluorescence studies at a variety of solution pHs and aluminum concentrations have been used to determine the most probable species in solution and binding constants of the complexes formed. The fluorescent chelating agent descriid in this paper can be used for the rapid determination of unperturbed free aluminum in aqueous solution.
