    Facilitated transport of Pb(II) ions in acidic medium, across a supported liquid membrane (SLM) by using 5,11,17,23-tetra-tert-butyl, 25,27-bis(benzylamino etoxy)-26,28-dihydroxycalix[4]arene as carrier, dissolved in kerosene, has been investigated. The parameters studied are Pb(II) ions concentration in the feed phase, HCl concentration in the stripping phase, and solvent effect in the membrane phase. The Celgard 2500 membrane was used as the solid support. A Danesi mass transfer model was used to calculate the permeability coefficients for each parameter studied. Also, AFM technique and contact angle measurements were used to characterize the surface morphology of the prepared Celgard 2500-carrier 1 SLM.
