Abstract

An improved method for the fluorophotometric determination of trace Al(III) has been developed. This method involves a fluorescence quenching reaction that results in the formation of an m-carboxyphenylfluorone-Al(III) complex in a poly(N-vinylpyrrolidone) micellar medium. The calibration curve was found to be linear in the range of 0.03-1.50 μg dm-3. We successfully applied the proposed method to an assay of Al(III) in canned beverages, which required only sample dilution and no sample pretreatment. The proposed method is expected to determine Al(III) in a simple and rapid manner. 2011
