Abstract
Boron or uranium isotopes can be chemically separated and enriched with high speed and with high separating efficiency by using weakly basic anion exchange fibers having a diameter of not more than 100 .mu., an aspect ratio of at least 5 and an exchange capacity of at least 2 meq/g-dry fiber, which are packed in a column at a specific volume of 2.0 - 20.0 ml/g-dry fiber.
Claims9
A method for separation and enrichment of isotopes, which comprises
- loading a solution containing anions of a mixture of isotopes of an element selected from the group consisting of boron and uranium into weakly basic anion exchange fibers which have a diameter of not more than 100 .mu.m, a length of not more than 5 mm, an aspect ratio of at least 5 and an exchange capacity of at least 2 meg/g-dry fiber, and which are packed with a specific volume of 2.0 - 20.0 ml/g-dry fiber and
- then eluting said anions with an eluting agent at a temperature of 0.degree.-100.degree. C.
