Abstract

Abstract 10B is more fractionated to B(OH)L {H2L: a ligand having a bis(2-hydroxyalkyl)amino group (alkyl: ethyl and propyl)} with a tetrahedral coordination mode than to B(OH)3 with a planar triangular coordination mode in aqueous solutions, exhibiting an isotope separation factor of 1.027 at 25 °C, which is greater than the upper limit of anion exchangers.
