化学交换法分离锂同位素研究进展
Research progress of lithium isotope separation by chemical exchange method
摘要
Abstract
Lithium isotopes(lithium-6 and lithium-7),as important raw materials required in the development of nuclear energy,play a great role in energy,environment,defense-national security, and other fields. The chemical exchange methods for lithium isotopes separation include amalgam exchange process,solvent extraction,chromatography and membrane method. The separation mechanisms,advantage and disadvantage of various lithium isotopes separation methods,have been systematically analyzed,classified and summarized in this paper. The results indicated that lithium isotope separation is related to the bond effect of complexing agent and lithium ionic in the chemical exchange separation system;and lithium amalgam exchange process will be replaced by other non-mercury separation systems due to environmental concerns. In addition,the lithium isotopes separation methods of using solvent extraction,ion exchange chromatographic and membrane are very promising,which all are relatively effective separation . Based on the summarization of the current research progresses,the future researches on the separation of lithium isotopes are highlighted,such as the design and synthetics of new chelating agent,the combination of different separation process and the separation mechanism in different experiment condition.关键词
