Abstract

EDTA and TTHA solutions were used as terminating electrolytes and 10 mM HCl containing 45% (v/v) acetone as the leading electrolyte. Gd, Eu, Sm. Pr, Ce and La ions were separated as their anionic chelates when EDTA was used as the terminating ion. The migration order of the chelates was in accord with the order of their stability constants.
