Abstract

The substoichiometric separation of lanthanum was studied on the system EDTA —lanthanum—8-hydroxyquinoline. The optimum conditions for the substoichiometric separation of lanthanum were calculated theoretically and these results were examined experimentally. By using the two chelating agents, EDTA and 8-hydroxyquinoline, lanthanum could be separated substoichiometrically with good accuracy and precision. This method was applied to the determination of lanthanum by activation analysis, and found to be available for the determination of trace amount of lanthanum.
