Emulsion liquid membrane pertraction of benzimidazole using a room temperature ionic liquid (RTIL) carrier

Emulsion liquid membrane for heavy metal removal: An overview on emulsion stabilization and destabilization

“…Nevertheless, most of investigators revealed that the size of internal droplets decreased with the increase of the emulsification speed and time up to a certain level by maintaining other parameters remain constant [16,[20][21][22][23][24][25]. Venkatesan and Begum [21,22] prepared W/O emulsion at 2,000-12,000 rpm for 2-10 min using a high-speed homogenizer. In their conclusion, the optimum conditions could be achieved around emulsification speed 10,000 rpm for 6 min which gave lower breakage.…”

Ionic liquids in supported liquid membrane technology

“…The main disadvantage of an organic emulsion liquid membrane is stability issue. Emulsion swelling is critical for this operation, where osmotic swelling [32] occurs during permeation of solute into emulsion droplets. (iii) Before starting the processes the medium has to be produced, which should be stable enough to reduced the leakage quantity, but still not very stable so that they could be destroyed after the separation.…”

Pseudo-emulsion based hollow fiber with strip dispersion pertraction of iron(III) using (PJMTH+)2(SO42−) ionic liquid as carrier

“…On the other hand, ionic liquids or "green solvents" are a group of organic salts that exist as liquids at a temperature below 100 • C. Due to some specific features that they presented, these compounds have been used for several applications in many fields as well as they are proposed for separation processes of metals and other solutes [8][9][10][11][12][13][14][15][16][17].…”
