Osmotic water transport through carbon nanotube membranes.
We use molecular dynamics simulations to study osmotically driven transport of water molecules through hexagonally packed carbon nanotube membranes. Our simulation setup comprises two such semipermeable membranes separating compartments of pure water and salt solution. The osmotic force drives water flow from the pure-water to the salt-solution compartment. Monitoring the flow at molecular reso...
متن کاملSupported liquid membranes : instability effects
The instability behaviour of several supported liquid membranes (SLMs) has been studied for a system in which nitrate ions are removed from an aqueous feed phase and concentrated in a stripping phase. The composition of the aqueous phases and of the membrane liquid has been determined after the aqueous phases had flowed parallel to the membranes for a period of six days. From the experimental d...
متن کاملArsenic Removal by Liquid Membranes
Water contamination with harmful arsenic compounds represents one of the most serious calamities of the last two centuries. Natural occurrence of the toxic metal has been revealed recently for 21 countries worldwide; the risk of arsenic intoxication is particularly high in Bangladesh and India but recently also Europe is facing similar problem. Liquid membranes (LMs) look like a promising alter...
متن کاملReview on Mechanism of Facilitated Transport on Liquid Membranes
Membrane processes are used in various felds such as the environment, agriculture and different industrial sectors. These clean techniques are often adopted for directed processes such as treatment, recovery, valorization and separation. In this review article, the theoretical principles and the different classifcations of liquid membranes, such as supported liquid membra...
متن کاملOsmotic Flow of Water across Permeable Cellulose Membranes
Direct measurements have been made of the net volume flow through cellulose membranes, due to a difference in concentration of solute across the membrane. The aqueous solutions used included solutes ranging in size from deuterated water to bovine serum albumin. For the semipermeable membrane (impermeable to the solute) the volume flow produced by the osmotic gradient is equal to the flow produc...
