Abstract

The adsorption and separation behaviors of transition metal ions using a merrifield resin bound 1,12-diaza-3,4:9,10-dibenzo-5,8-dioxacyclopentadecane (NTOE) and 1,12,15-triaza-3,4:9,10-dibenzo-5,8-dioxacycloheptadecane(NDOE) were investigated in aqueous solution. The orders of adsorption degree(E) and distribution ratio(D) of transition metal ions were Cu(II)$t_R$) of metal ions were affected by adsorption degree(E) and distribution ratio(D). This results showed good separation efficiency of Ag(I) from mixed metal solution.

수용액에서 1,12-diaza-3,4:9,10-dibenzo-5,8-dioxacyclopentadecane(NTOE)가 결합된 merrifield 수지와 1,12,15-triaza-3,4:9,10-dibenzo-5,8-dioxacycloheptadecane(NDOE)가 결합된 merrifield 수지를 이용한 전이금속이온들의 흡착 및 분리특성을 조사하였다. 전이금속이온들의 흡착정도(adsorption degree, E)와 분포비(distribution ratio, D)의 순위는 동일하게 Cu(II)$t_R$)이 흡착정도와 분포비에 의해서 영향을 받았으며, 이러한 흡착 및 분리 실험 결과로부터 혼합금속용액에서 Ag(I)의 분리가능성을 확인할 수 있었다.
