The permeation of Co(II) and Pb((II) ions from an aqueous feed solution through a ceramic disc supported liquid membrane impregnated in D2HEPA as a carrier was studied. The effects of Co (II) and Pb (II) ions, HNO3 in feed phase and D2HEPA in kerosene, EDTA as stripping solution (0.1-2) mol/L in ceramic membrane concentrations have been studied. The concentration of cations increase in the feed phase due to an increase in flux from (15.8-21.2)×10−9 in the Co(II) and (7.22-14.83)x10-9 mol/m2.s in Pb(II) ions, concentration in the range (7.98–26.45)×10−4 mol/L for cobalt and(5.66-13.71)x10-4 mol/L for lead ions respectively, [H3O]+ increasing with [NO3]- from 2 mol/L results into an increase in cobalt ions flux.The optimum conditions for Co (II) ions transport at 2mol/L HNO3 in feed phase and 2mol/L D2HEPA in ceramic membrane. It has been showed that cobalt and lead ions in flux increases. Applying the studied conditions indicated more than 98.7% removal of Co(II) ions and 66.4% of Pb (II) respectively.
