Electrospray ionization mass spectrometry (ESI‐MS) has been applied to the study of solution equilibria between Al(III) and the two ligands 4‐hydroxy‐3‐pyridinecarboxylic acid (4H3P) and 3‐hydroxy‐4‐pyridinecarboxylic acid (3H4P). The results compare well with the speciation data obtained from potentiometric, UV‐visible spectroscopy, and NMR measurements. This agreement suggests the applicability of ES‐MS to the study of more complicated aluminium–ligand systems. Copyright © 2003 John Wiley & Sons, Ltd.
