Transport of Zr ions through tri-n-octylamine and di-cylohexylamine xylene based liquid membranes supported in polypropylene microporous films has been studied and found that HNOJ is a better acid in the feed and water and methyl-succinic acid are the stripping agents which can be used to transport Zr ions. The values of flux (J) and permeability coefficient (p) for Zr (IV) ions under optimum conditions from HNOJ feeds to water stripping phase across the membranes are 19.4x J 0.6 mol.m·'.s·' and 19.90x I 0.10 m'.s·'respectlvley. In case of methyl succinic acid as stripping agent the values of J and Pare 1.9x 10.6 mol.nf'.s·land 1.78xI0·" m'.s·' respectively. Di-cyclo-hexylamine is not a slIltable camel' to separate Zr iom using coupled transport system
