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.
电喷雾电离质谱（ESI-MS）已应用于研究铝（III）与两种配体4-羟基-3-吡啶羧酸（4H3P）和3-羟基-4-吡啶羧酸（3H4P）之间的溶液平衡。结果与通过电位滴定法、紫外可见光谱法和核磁共振测量获得的物种形成数据吻合良好。这种一致性表明ESI-MS适用于研究更复杂的铝-配体体系。
