초록

유화형 액막을 이용하여 D₂EHPA-Kerosene-Span 80-H₂SO₄ 계에서 Zn 성분의 추출시 액막의 안정성에 영향을 미치는 에멀젼의 파괴, swelling 현상 및 에멀젼의 morphology를 조사하였다. Zn 성분의 추출시 액막의 안정성에 대한 최적 조건은 계면활성제 Span 80의 농도 2∼3 vol.%, 추출담제 D₂EHPA의 농도 5∼7 vol.%, 막강화제 paraffin oil의 농도 10 vol.% 였으며, 외부수용액에 대한 에멀젼의 비 0.1, 유기상에 대한 내부수용액의 비는 1.0이 적절하였다.

The stability of liquid membrane in the extraction process was investigated through the extraction of the Zn component by using W/O/W emulsion type liquid surfactant membrane which was D₂EHPA-Kerosene-SPan 80-H₂SO₄ system. The highest stability for liquid membrane through the Zn extraction process was obtained under the following conditions. That conditions were that span 80 concentration, as surfactant, of 2∼3 vol.%;D₂EHPA concentration, as extractant, of 5∼7 vol.%;paraffin oil concentration, as membrane strengthening agent, of 10 vol.%;emulsion volume ratio to the external aqueous phase volume of 0.1, and internal aqueous phase volume ratio to the organic phase volume of 1.0.
