The process of separation of oil and water. Here, water colored blue by Cu(NO3)2 was used for clarity.
(a) cyclohexane was used as a kind of oil lying on the upper layer while water at the bottom layer. After suction filtration, the cyclohexane was stopped on the membrane while the blue aqueous solution passed through the membrane. (b) a process similar to that in (a) except that carbon tetrachloride was used as another kind of oil lying at the bottom layer while water at the upper layer. (c) emulsion, taking water/cyclohexane system as an example, was successfully separated.
