中文摘要：
现有锂汞齐法因大量使用有毒汞不能满足民用核能对锂同位素分离要求；设计合成系列新型螯合剂和离子液体；采用实验与量子化学计算相结合，研究离子液体理化性质（粘度、密度和憎水性等）和微环境（极性、离子分布和团簇行为），并探讨离子液体结构与性质关系的规律性；建立单级萃取实验模型，考察不同萃取体系锂同位素分离行为，结合对螯合缔合物结构的研究，提出锂同位素分离的规律和机理；建立逆流串级全流程实验模型，研究体系物料性质对同位素交换速率、级联效率和性能稳定性的影响；在深入研究螯合剂和离子液体的结构、性质及分离行为内在关系基础上，完善设计思想，应用于指导构建绿色高效的锂同位素萃取分离体系。研究成果应用于锂同位素分离，可显著提升民用核能发展所需高纯锂6和锂7生产效能，消除因使用毒性汞和有机溶剂而带来的环境和健康问题。项目完成可使我国在同位素萃取分离领域的研究进入国际前沿，对促进国际学术及人才培养具有重要意义。
