Estimating the term…
A lithium isotope concentration device includes a treatment tank partitioned in a supply tank and a recovery tank by an electrolyte membrane having a lithium-ion conductivity. The electrolyte membrane is cooled by a cooling device via an Li-containing aqueous solution in the supply tank to have a low temperature at which the Li isotope separation coefficient is larger. A power supply device, connected between electrodes provided on opposite surfaces of the electrolyte membrane, applies a positive voltage to an electrode on a supply tank side.
A lithium isotope concentration device which includes a treatment tank partitioned into a first tank and a second tank and which recovers, from an aqueous solution being held in the first tank and containing 6Li and 7Li in a state of lithium ions, a lithium ion-containing aqueous solution having a higher isotope ratio of 6Li than that of the aqueous solution into the second tank, the lithium isotope concentration device comprising:
