A model for metal ion pertraction through supported liquid membranes

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 coefficient have been suggested and found that the equation in the form of k=aRefn1Scfn2Gorgn3 has the best agreement with experimental data. The average deviation between experimental and calculated data was found to be 19.93% for this model.
