Resumen:
During the last three decades, the use of rare earth
elements (REEs) in manufactured goods have resulted in a wide variety of
electromechanical and metallurgical devices to glasses, superconductors,
supermagnets, lasers and electronic components. The separation and
determination of REEs analytes are especially challenging due to the similarity
in chemical characteristics arising from their equal charge and almost similar
ionic radii. In the present work, the implementation of a new method for the simultaneous
determination of two rare earth elements at picogram per liter levels by
on-line coupling of a solid-phase preconcentration step to capillary zone
electrophoresis with diode array detection is demonstrated.
