Abstract

음이온과 비이온 계면활성제를 사용한 액막에 의하여 벤젠과 싸이클로헥산 혼합물을 분리함에 있어서 외부유상에 친유성 계면활성제를 투여하여 외부유상의 유화액적의 크기를 미세화시킴으로써 분리능을 향상시키기 위하여 HLB값이 다른 3종류의 친유성 계면활성제를 사용하였다. 비이온 계면활성제의 경우 친유성 계면활성제를 사용하지 않은 경우보다 투과율 및 분리계수가 크게 증가하였다. 그러나 음이온 계면활성제의 경우에는 사용하지 않은 경우에 비하여 투과율과 분리계수가 약간의 증가를 나타내어 분리능의 향상은 크지 않았다. 또한 투여한 친유성 계면활성제의 농도가 증가함에 따라 비이온과 음이온 계면활성제의 경우 공히 막파괴율이 증가하였다.

To increase the separability of benzene-cyclohexane mixture by liquid membranes with anionic and nonionic surfactants, lipophilic surfactants of different HLB values were injected into the external oil phase for the purpose of making the size of emulsion globules smaller. In the case of nonionic surfactant the fraction of permeation and the separation factor increased appreciably compared with those obtained without using lipophilic surfactants. In the case of anionic surfactants, however, the fraction of permeation and the separation factor did not increase appreciably compared with those obtained without using lipophilic surfactants. In general the percentage of membrane breakup was more when the lipophilic surfactants were added than not.
