ISOTOPE SEPARATION METHOD, ISOTOPE SEPARATION APPARATUS AND ISOTOPE SEPARATION MEANS

摘要

PROBLEM TO BE SOLVED: To provide an isotope separation capable of efficiently separating or concentrating the isotope of an alkaline metal element and an alkaline earth element without using environmental pollution materials such as a mercury, by an isotope separation method in which separation factor is large and an exchange rate of isotope is fast, in other words, a height of separation stage is small.;SOLUTION: This invention provides an isotope separation method which is comprised of a process passing a solution of alkaline metal element and alkaline earth element through a separation column filled with a resin containing a cyclic compound functional group and an anion exchange group. And a process separating a prescribed suction area of the solution by using a chromatography. And this invention also provides an isotope separation apparatus 10 which has a separation means containing porous particles 28 which support a resin containing the cyclic compound functional group and the anion exchange group. The separation means of this invention is deemed to be the separation column 14 filled with porous particles 28 supporting the resin.;COPYRIGHT: (C)2005,JPO&NCIPI
