Abstract
벤젠과 싸이클로헥산의 혼합물을 액체막에 의하여 분리함에 있어서 계면활성제의 종류와 농도, 접촉온도가 투과율, 분리계수 및 막의 안정성에 미치는 영향을 분석하였다. 음이온 계면활성제를 사용한 경우 그 농도와 접촉온도가 증가함에 따라 두 성분의 투과율은 증가하였으나 비이온 계면활성제의 경우에는 일관성있는 경향을 보여주지 않았다. 비이온 계면활성제보다 음이온 계면활성제를 사용했을 때 더 높은 투과율과 분리계수를 얻을 수 있다. 사용한 모든 계면활성제의 경우 접촉온도가 상승함에 따라 막파괴율은 증가하였다.
In the separation of a mixture of benzene and cyclohexane by liquid surfactant membrane, investigated was the effect of surfactants and their concentration of the permeability, separation factor and membrane stability for different contact temperatures. In the case of anionic surfactants the fraction of permeation increased as their concentration and contact temperature increased, however, no consistent trend was observed in the case of nonionic surfactants. Higher permeability and separability were achieved with anionic surfactants than with nonionic ones. For all the surfactants used percentage of membrane breakup increase as the contact temperature increased.
