摘要: Inorganic ion exchangers in hydrogen forms, H0.36La0.55TiO3 (HLTO), H4Ti5O12 (HTO12) and H2Ti3O7 (HTO7) have been prepared by acid treatment of Li0.36La0.55TiO3, Li4Ti5O12 Li2Ti3O7, respectively, which were synthesized the solid-state reaction method. The selectivity metal ions, Li+ exchange property lithium isotopes separation investigated. three isotopically 6Li-specific, maximum single-stage factors 6Li/7Li, 1.042, 1.037 1.035 for HLTO, HTO12, HTO7, respectively. structures HTO12 HTO7 stable they can be regenerated recyclable cycles.
