Selective transport of polyfunctional cations through bulk liquid membranes assisted by macrocyclic polyethers

Selective Mass Transport of CO2 Containing Mixtures through Zeolite Membranes

In this work, the main aspects regarding the permeation of mixtures containing CO2 and permanent gases such as H2 , N2 and CH4 through zeolite membranes have been investigated, focusing on the description of the mass transport mechanisms taking place inside the pores. First, a brief overview about the performance of the main zeolite membranes used in gas separation (e.g. DDR, CHA, AEI, FAU, etc...

Selective Transport of Propylene by Silver Ion Complex Through an Immobilized Liquid Membrane

SELECTIVE TRANSPORT AND EXTRACTION OF ALKALI METAL CATIONS (Na & K ) THROUGH CHLOROFORM LIQUID MEMBRANE BY DIETHYLENE GLYCOL MONOBUTYL ETHER AND DIETHYLENE GLYCOL DIBUTYL ETHER

A liquid membrane containing diethylene glycol monobutyl ether (2) shows specificity for K ion in transport while diethylene glycol dibutyl ether (1) was selective for Na over K . As an extractant, ligand 2 exhibited pronounced extraction selectivity for K over Na in comparison with ligand 1

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 ...
