LITHIUM ISOTOPE CONCENTRATOR, MULTISTAGE LITHIUM ISOTOPE CONCENTRATOR, AND LITHIUM ISOTOPE CONCENTRATION METHOD

摘要

To provide a safe and highly-efficient lithium isotope concentrator, and a lithium isotope concentration method, by electrodialysis.SOLUTION: In a lithium isotope concentrator 10 including a treatment tank 1 partitioned into a feed tank 11 and a recovery tank 12 by a lithium ion conductive electrolyte film 2, a positive voltage +Vis applied intermittently to an electrode 31 on the feed tank 11 side by a power supply 5 connected between each electrode 31, 32 provided on both surfaces of the electrolyte film 2, to thereby repeat the state where an isotope separation coefficient just after operation start is large in electrodialysis.SELECTED DRAWING: Figure 1
