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