LITHIUM ISOTOPE SEPARATING AGENT AND SEPARATING PROCESS FOR LITHIUM ISOTOPE

摘要

PROBLEM TO BE SOLVED: To provide a separating agent and a process thereof for separating ⁶Li from ⁷Li which can synthesize the separating agent easily, can be used repeatedly and can treat a large amount of lithium ions by using a small amount of the separating agent. ;SOLUTION: A lithium isotope separating agent is formed of a bis(1,10- phenanthroline) derivative represented by the formula. In the process of carrying lithium ions contained in a solution to a lithium acceptive liquid through a cation carrying agent, the above-referred lithium isotope separating agent is used as an ion carrying agent, and ⁶Li ions are carried selectively in the acceptive liquid. In the formula, R represents hydrogen or a hydrocarbon, and (n) represents integers of l-10.;COPYRIGHT: (C)1998,JPO
