수용액에서 poly-dibenzo-18-crown-6를 이용한 알칼리, 알칼리토금속이온 및 전이금속이온들의 흡착 및 분리특성을 조사하였다. 알칼리금속이온들과 알칼리토금속이온들의 흡착정도와 분포비의 순위는 각각 Li(I)<Na(I)<K(I) 와 Mg(II)<Ca(II)<Sr(II)를 나타내었다. 전이금속이온들의 흡착정도와 분포비의 순위는 Cu(II)<Ni(II)<Co(II)<Cd(II)<Pb(II)<Ag(I)로 나타났다. 또한 Li(I)-Na(I)-K(I), Mg(II)-Ca(II)-Sr(II), Cu(II)-Cd(II)-Ag(I) 와 Ni(II)-Co(II)-Pb(II)의 혼합금속용액에서의 금속이온들의 용리곡선을 조사한 결과 이들 이온의 머무름시간이 흡착정도와 분포비에 의해서 영향을 받았으며 K(I), Sr(II), Ag(I) 와 Pb(II)의 분리가능성을 확인할 수 있었다.
The adsorption and separation behaviors of alkali, alkaline earth and transition metal ions using a poly-dibenzo-18-crown-6 were investigated in aqueous solution. The adsorption degree(E) and distribution ratio(D) of alkali, alkaline earth metal ions were Li(I)<Na(I)<K(I) and Mg(II)<Ca(II)<Sr(II), respectively. The adsorption degree(E) and distribution ratio(D) of transition metal ions was Cu(II)<Ni(II)<Co(II)<Cd(II)<Pb(II)<Ag(I). Also, from the elution curves for mixed metal solution of Li(I)-Na(I)-K(I), Mg(II)-Ca(II)-Sr(II), Cu(II)-Cd(II)-Ag(I) and Ni(II)-Co(II)-Pb(II), the retention time(<TEX>$t_R$</TEX>) of metal ions were affected by the adsorption degree(E) and distribution ratio(D). This results showed good separation efficiency of K(I), Sr(II), Ag(I) and Pb(II) from the mixed metal solution.
