Abstract

Lithium isotope separation on molecular complex formation has been studied in lithium chloride- 1, 4-dioxane systems. The complex shows an absorption maximum at 270 mμ, and the molar ratio LiCl/dioxane in the complex has been found to be 1:1. The isotope ratio has been determined by a mass spectrometer using a surface ionization ion source. The results show that Li is enriched in the complex and the single stage separation factor is 1.026 in equilibrium at 100 °C. The separation of lithium isotopes seems to occur during the isotope exchange reaction between LiCl-dioxane complex and uncomplexed LiCl.
