FUNDAMENTAL STUDIES ON THE ION EXCHANGE SEPARATION OF ISOTOPES, (111) CONTINUOUS ENRICHMENT OF LITHIUM ISO TOPES BY A SIMULTANEOUS USE OF ION EXCHANGE AND ELECTRO MIGRATION

摘要

A number of studies has been published on the -isotope separation using ion exchange chromatography or electromigration but some difficulties still remain to be solved for the continuous operation of these separation pro¬cesses.nA new type of apparatus was devised on the basis of simultaneous use of. ion exchange and electromigration for a continuous isotope enrichment.nTo examine the efficiency of this apparatus, the experiments on lithium isotope separation were carried out. At the stationary state of continuous operation, the separation factors of Li2C03 system and LiOH system were found to be 1.0069 and 1.0049 respectively.
