ANION EXCHANGE OF METAL COMPLEXES Ⅶ. THE LANTHANIDES - NITRATE SYSTEM

摘要

Previous results for the distribution of the lighter lanthanides between nitrate solutions and a strongly basic anion exchanger are extended by data for the heavier lantha¬nides. An odd-even Z effect, previously observed in sol¬vent extraction studies, is also found in this work. The extraction of the lanthanides by a long chain amine is de¬scribed briefly. The results are interpreted in terms of nitrate complex formation and changes in the hydration of the lanthanides in nitrate solutions.
