[환경] Mono - Crown Ether와 Bis - (Crown Ether)s를 이용한 알칼리금속과 알칼리토금속 양이온들의 용매추출

Solvent extraction of alkali metal and alkaline earth metal cations by mono-crown ether(benzo-15-crown-5) and bis-(crown ether)s(ethylenediamine bis(4'-formyl benzo-15-crown-5)) containing benzo-15-crown-5 moieties were investigated with water-chloroform system at $25^{\circ}C$. The order of th...

description Solvent extraction of alkali metal and alkaline earth metal cations by mono-crown ether(benzo-15-crown-5) and bis-(crown ether)s(ethylenediamine bis(4'-formyl benzo-15-crown-5)) containing benzo-15-crown-5 moieties were investigated with water-chloroform system at $25^{\circ}C$. The order of the extraction equilibrium constants($K_e$) and the complexation constants($K_c$) for the alkali metal and alkaline earth metal cations with mono-crown ether and bis-(crown ether)s were Ca(II)>Na(I)>Sr(II)>K(I)>Mg(II)>Rb(I) and Sr(II)>Ca(II)>K(I)>Rb(I)>Mg(II)>Na(I) respectively. These results were explained in terms of the size effect of metal cation and electron density effect. Also, the bis-(crown ether)s was found to extract metal cations more effectively than the corresponding mono-crown ether. mono-crown ether(benzo-15-crown-5)와 benzo-15-crown-5를 포함한 bis-(crown ether)s(ethylenediamine bis(4'-formylbenzo-15-crown-5))에 의한 알칼리금속과 알칼리토금속 양이온들의 용매추출을 $25^{\circ}C$, 물-클로로포름계에서 조사하였다. mono-crown ether와 bis-(crown ether)s를 사용한 경우 알칼리금속과 알칼리토금속 양이온들에 대한 추출평형상수($K_e$)와 착물형성상수($K_c$)의 크기 순위는 각각 Ca(II)>Na(I)>Sr(II)>K(I)>Mg(II)>Rb(I)와 Sr(II)>Ca(II)>K(I)>Rb(I)>Mg(II)>Na(I) 순으로 증가하였다. 이들 크기 순위는 금속 양이온의 크기 및 전자밀도효과로서 설명할 수 있었다. 또한 mono-crown ether에 비해서 bis-(crown ether)s를 사용한 경우 금속양이온들에 대한 추출효율이 좋게 나타남을 알 수 있었다.
