SEPARATION OF METALS BY LIQUID MEMBRANE WITH TRI-n-OCTYLAMINE

Abstract

The separation of iron and zinc was studied with the use of liquid membrane containing tri-n-octylamine in benzene. The selective separation of zinc and iron can be performed with the help of the strong difference in permeation rates between the two metals. Simultaneous enrichment of zinc and iron can be realized if a proper condition is selected, i.e., the condition that fluxes of both zinc and iron are controlled by the diffusional resistance in the raffinate aqueous phase.
