A New Principle of Isotope Enrichment by Chemical Methods

研究了一种新的锂同位素富集离子交换方法。该方法是基于lta -沸石上锂吸附的旋多分解。该方法采用洗脱法分离沸石离子交换柱中富集锂-7的部分。剩余的锂-6富集部分由另一种洗脱液获得。切换洗脱液，得到富集的同位素产物。派系收集者是不必要的。该方法可用于同位素富集的基本过程。

A new ion-exchange method for the isotope enrichment on lithium has been studied. This method is based on the spinodal decomposition of the lithium absorption on LTA-zeolite. The new method separates the lithium-7 enriched part of the ion-exchange column of zeolite by elution. The rest of lithium-6 enriched part acquired with another eluent. Switching the eluents, the enriched isotope products are obtained. Faction collectors are unnecessary. This new methodmay be useful for the elementary processof isotope enrichment.
