Four kinds of phenol-formaldehyde resins containing benzo-15-crown-5 ether were synthesized for lithium isotope separation.The adsorption capacity and isotope effect of Li⁺ in these resins have been investigated.Single separation factors 1.023~1.056 were obtained with batch method from isotope ratios,⁶Li⁺ and ⁷Li⁺ were enriched in the resin phase and liquid phase,respectively.
