Abstract

Separation of lithium isotopes was investigated by chemical ion exchange with a hydrous manganese(IV) oxide ion exchanger using an elution chromatography. The capacity of manganese(IV) oxide ion exchanger was 0.5 meq/g. The heavier lithium isotope was enriched in the solution phase, while the lighter isotope was enriched in the ion exchanger phase. The separation factor was determined according to the method of Glueckauf from the elution curve and isotopic assays. The separation factor of $^6Li^+$-$^7Li^+$ isotope pair fractionation was 1.018.

용리 크로마토그래피를 사용하여 가수된 산화 망간(Ⅳ)이온교환체로 화학적 이온교환을 통하여, 리튬 동위원소를 분리하는 연구를 하였다. 산화 망간(Ⅳ)이온교환체의 이온교환 용량은 0.5meq/g이었다. 무거운 리튬 동위원소는 용액상에, 그리고 가벼운 동위원소는 이온교환 수지상에 농축되었다. 분리인자는, Glueckauf의 방법으로 용리곡선과 동위원서 분석 값들로부터 구하였다. $^6Li^+$-$^7Li^+$ 동위원소쌍의 분별로부터 얻은 분리인자의 값은 1.018이었다.
