Supported liquid membrane

Separation of benzene and cyclohexane is one of the most challenging processes in the chemical industry. In our previous paper, we examined the separation of a mixed solution of benzene and cyclohexane using a supported liquid membrane (SLM) based on ionic liquids. In this study, vapor permeation (V

The transport of cationic dyes methyl violet and rhodamine B from aqueous synthetic dye solution through flat type supported liquid membranes (SLM) using di (2-ethylhexyl) phosphoric acid (D2EHPA) as carrier was studied and the parameters affecting the dyes transport were determined. The extraction

A supported liquid membrane was prepared by impregnation of commercial microporous polymer film with methyl cholate in cyclohexane and was used to study transport of various sugars. The stability constant and apparent diffusion coefficient of carrier-sugar complex were determined. The absence of a p

Facilitated transport of Cs-137 across supported liquid membranes (SLM) containing a calix-crown ligand viz. calix[4]arene-bis(crown-6) (CC), calix[4]arene-bis(o-benzocrown-6) (CBC) or calix[4]arene-bis(napthocrown-6) (CNC) was investigated. The feed consisted of dilute nitric acid solutions while t

Zinc has been permeated through a flat-sheet supported liquid membrane, using 2-ethylhexylphosphoric acid mono-2-ethylhexyl ester (PC-88A) in kerosene. Liquid–liquid experiments were conducted as a function of aqueous pH (1–6) to establish optimum conditions for both extraction and stripping of the

A supported liquid membrane (SLM) contains organic solvent and organic extractant as one organic phase, and a porous support structure. It has been widely investigated for separation and purification of various chemical compounds. SLM has high permeability and selectivity, being regarded as one of t

Transport of metal ions through supported liquid membranes has been investigated. A general dimensionless model for mass transfer coefficient is proposed which consists of diffusional, equilibrium and process parameters also properties of the membrane. Nine dimensionless equations for mass transfer

Transport of uranyl ion from HCl medium was investigated using 0.2 micron PTFE filters as the membranesupport and 30% alamine 336 in toluene as the carrier while distilled water was used as the strippant. In an experimentcarried out to understand the effect of the organic diluents, the observed tren

The extraction of short peptides through a supported liquid membrane containing di-2-(ethylhexyl)phosphoric acid (D2EHPA) as a carrier was investigated. The extraction was carried out from the aqueous donor phase with pH 3 to a more acidic acceptor phase. The proton gradient between the donor and th

Ion-size recognition of three trivalent metal ions (Fe(III), Al(III), Cr(III)) with 3-phenyl-4-acyl-5-isoxazolones derivatives has been studied by the liquid-liquid extraction method. The diffusion of the corresponding complexes with Fe(III) in supported liquid membrane (SLM) system has been evaluat
