O/W/O형 Emulsion 액체막에 의한 Toluene과 n-Heptane 혼합물의 분리(제1보)

Separation of Toluene/n-Heptane Mixture by O/W/O Type Emulsion Liquid Membrane(part 1)

In the separation of toluene/n-heptane mixture by the emulsion type liquid membrane in a batch system, the effect of surfactant on the separation factor and membrane stability was studied over the surfactant concentration ranging from 0.1 to 1.5wt% at the contact time of 5 and 10 minutes. and the settling time of 5 and 10 minutes. The surfactant used was sodium lauryl sulfate. The separation factor reached its maximum value at the surfactant concentration of 0.5wt% for surfantant. It was found that the percentage of membrane breakup reached its minimum values and the separation factor showed its maximum value at the surfactant concentration of 0.5wt%, which confirmed that efficient separation could be effect when emulsion liquid membrane was stable because of low membrane breakup.
