Mathematical modeling for facilitated transport of Ge(IV) through supported liquid membrane containing Alamine 336

Selective and Facilitated Transport of Vanadium (VO2 +) Ion through Supported Liquid Membrane and Effects of Membrane Characteristics

A new supported liquid membrane (SLM) system for the selective transport of VO2 ions was prepared in this present work. The SLM was a thin porous polyvinylidene difluoride (PVDF) membrane soaked with Di-(2-ethylhexyl) phosphoric acid (D2EHPA) as mobile carrier in Xylene as organic solvent. D2EHPA acts as a highly selective carrier for the uphill transport of VO2 ions through the SLM. The transp...

Review 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...

A Kinetic Investigation of a Carrier-Mediated Transport through a Bulk Liquid Membrane

The kinetics of the potassium thiocyanate transport mediated by dicyclohexyl-18-crown-6 (L) through a bulk liquid membrane is studied experimentally and theoretically. The proposed model is based on the assumption of a pure diffusion of the complex salt [K·L]+SCN¯ through the liquid membrane stagnant films at the interfaces. It illustrates the ...

Facilitated Transport Membrane Systems

R. D. Noble, a research profissor in chemical engineering at the Univ. of Colorado, specializes in the use of reversible chemical reactions in chemical gas and liquid separation processes, most notably the use of ion-exchange membranes as supports for complexing agents and the modeling and analysis of various facilitated transport systems. Refore joining the Univ, of Colorado, he served as an a...
