A method based on separation with ion chromatography and post-column fluorescence detection has been developed for the determination of Al(III), Cd(II), Ga(III), ln(III) and Zn(II). AI(III) and Ga(III) separation was achieved by an eluting system containing two ligands namely pyridine-2,6-dicarboxylic acid and tartaric acid. Calibration graphs were linear for at least two orders of magnitude for all analytes (10-2,000 mug/1) and detection limits ranged from 0.5 to 1.6 ng.

Abstract
A method based on separation with ion chromatography and post-column fluorescence detection has been developed for the determination of Al(III), Cd(II), Ga(III), ln(III) and Zn(II). AI(III) and Ga(III) separation was achieved by an eluting system containing two ligands namely pyridine-2,6-dicarboxylic acid and tartaric acid. Calibration graphs were linear for at least two orders of magnitude for all analytes (10-2,000 mug/1) and detection limits ranged from 0.5 to 1.6 ng.File in questo prodotto:
