✦ Synopsis

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 di †erent stirrer speeds in a permeation cell. An equation describing the permeation rate has been derived, taking into account stagnant layer aqueous di †usion and liquid membrane di †usion. By means of this treatment the copper overall transfer resistance and the experimental determination of the e †ective porosity factor (e/q), for each support have been performed. The 2E-PP membrane Accurel} showed a relatively high value of e/q (0É91), which makes this membrane an adequate support when the transport properties of the supported liquid membrane are concerned.
