The Selective Transport of Copper Ion through Supported Liquid Membrane

O. N. Ata

Abstract
The selective transport of copper (II) from an aqueous solution containing zinc, cadmium, nickel and cobalt through supported liquid membrane, using LIX 984dis - solved as a mobile carrier, was studied. The effects of components of organic and feed phases on the transport were investigated. The components of organic phase were given as; diluents: n-heptan, n-octan and kerosene, and polymeric membrane support materials: hydrophobic synthetic polymer membrane (Gorotex Teflon), poly (vinylidine difluoride) (Durapore HVHP). The component of feed phase is given as pH. The transport order for diluents and support observed as the feed phase pH increases is: n-heptan > n-octan > kerosene and teflon > durapore. Also, the results showed that Cd+2, Zn+2, Co+2 and Ni+2 ions were not transported at the pH range of feed phase studied, and 85.3 % of copper ions in the feed phase were transported.
