The effect of surface tension on the percentage of extraction of toluene as a function of the internal droplet radius, for separation of toluene from n-heptane, using emulsion liquid membrane with simple mechanism. The system has a globule with the radius of 30 µm, The initial numbers of moles are \(3.89\times {10}^{-10}\text{ mol}\) for toluene, \(3.57\times {10}^{-10 }\text{mol}\) for n-heptane, \(1.07\times {10}^{-9}\text{ mol}\) for water and \(1.5\times {10}^{-9}\text{ mol}\) for n-dodecane. The reservoir temperature and pressure are 298.15 K and 1 atm.
