The kinetics of Cu(II) transport through a bulk liquid membrane with different membrane materials was investigated in this work. Three types of membrane materials were used: fresh cooking oil, waste cooking oil and kerosene, each of which was mixed with di-2-ethylhexylphosphoric acid (carrier) and tributylphosphate (modifier). Kinetic models derived from the kinetic laws of two consecutive irre...

Humidification process is one of the applications of membrane contactor in which partial pressure of a vapor in the gas stream increases. In this study, two different polyethersulfone and polyetherimide hollow fiber membranes were fabricated and characterized by various test methods and their performance in humidification process under different operating conditions was investigated. The PES me...

The role of liquid membrane hypothesis has been studied in the mechanism of action of cephalosporins like cefuroxime sodium. In the present study transport of selected permeants (glucose, p-amino benzoic acid and ions like magnesium, ammonium, phosphate, calcium, sodium, potassium and chloride) through liquid membrane generated by cefuroxime sodium in series with supporting membrane has been st...

This is a comprehensive review of the recent progresses made in the field of zeolite membranes. It describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. Special attention is called to polymer mixed matrix membranes (MMMs) and membranes based on metal organic frame works (MOFs)....

Liquid–liquid extraction and liquid membrane transport behavior of tetravalent actinide ions viz. Th(IV), Np(IV), Pu(IV) were investigated for the first time using a diglycolamide (DGA) based dendrimer with tris(2-aminoethyl)amine (TREN) scaffold as organic extractant. The generation 1 six DGA pendent moieties (termed TREN-G1-DenDGA) extracted Np(IV) more effectively than other two ions, trend ...

A hybrid bilayer membrane is a planar model membrane that is formed at an alkanethiol monolayer-coated gold surface by the spontaneous reorganization of phospholipid vesicles. Membrane vesicles from monkey kidney COS-1 cells also reorganize at an alkanethiol/lipid monolayer-coated surface resulting in the formation of a cell membrane hybrid bilayer. Atomic force microscopy and spectroscopic ell...
