The transport of cadmium ions through a supported liquid membrane containing triethanolamine (TEA) as a mobile carrier has been studied. The effects of Cd(II) concentration, HCl in feed and car rier con cen tra tion in mem brane have been stud ied. Cd(II) con - cen tra tion in crease in feed leads to an increase influx from 2.1´10-7 to 8.4´10-7 mol cm-2 sec-1 within Cd(II) ions concentration range (2.7´10-4 M - 16.3´10-4 M) at 2.0 M HCl in the feed and 3.0 M triethanolamine in the membrane. Increase in H+ ion concentration from 0.5 M to 3.0 M results in an increase in Cd(II) ions flux but a decrease is observed beyond 2.0 M HCl concentration in feed. Increase in carrier concentration in the liquid inside the membrane enhances the flux with its maxima at 3.0 M carrier. Further increase in the concentration of TEA leads to a decrease in transport due to increase in viscosity of membrane liquid. The optimum conditions for Cd(II) ions transport are, 2.0 M HCl in feed, 3.0 M TEA in membrane and 0.1 M NaOH as strip solution. Similar transport characteristics have been observed for Cd-EDTA complexed anions across TEA- cyclo - hexanone based SLM, thus indicating a cadmium anion transport coupled with protons and chloride or EDTA co-ions.
