The coupled transport of copper(II) ions through a supported liquid membrane containing LIX 984 as the mobile carrier dissolved in kerosene has been studied. Many commercial membrane supports were investigated at different stirrer speeds in a permeation cell. An equation describing the permeation rate has been derived, taking into account stagnant layer aqueous diffusion and liquid membrane diffusion. By means of this treatment the copper overall transfer resistance and the experimental determination of the effective porosity factor (epsilon/tau), for each support have been performed. The Accurel(R) 2E-PP membrane showed a relatively high value of epsilon/tau (0.91), which makes this membrane an adequate support when the transport properties of the supported liquid membrane are concerned.
