Abstract
Capillary electrophoresis (CE) is a powerful tool for analytical separations. These separations are achieved based on analyte charge and size, allowing for the simultaneous separation and detection of positive, negative and neutrally charged species. The addition of complexing ligands to the background electrolyte solution further enhances separation efficiency. In this work, the separation of the group II metal cations including Be(II) and its hydrolysis products has been demonstrated. It was observed that surface geometry plays a role in elution order for these hydrolytic species. The hydrolysis of aluminum in the presence of hydroxycarboxylic acids was also investigated using CE and mass spectrometry. These experiments confirmed earlier observations of Al-27 NMR work. Finally, the separation of Al from Ga and other Group 13 metals and Fe(III) was pursued utilizing strongly complexing ligands.
