Enrichment of lithium isotopes

From a breakthrough experiment in the system [2. 2.1] resin/0.116 M methanolic LiCl solution (column height = 22 cm, diameter = 0.9cm), Nishizawa and co-workerswere able to calculate the following isotopic fractionation factors a = 1.047 (0 °C), a = 1.037 (30 °C). From the results of the batch and breakthrough experiments it follows that there is a promising possibility for an enrichment of lithium isotopes on a technical scale with the use of the [2b.2.1] cryptand resin exchanger.
