| Abstract: | Macrocycle-mediated transport of Eu3+ and Eu2+ from an aqueous solution through a modified thin-sheet-supported liquid membrane has been studied and compared with that of Sr2+, Gd3+ and Nd3+. Transport of Eu2+ was found to be more effective than that of trivalent lanthanide cations using bis (1-hydroxylheptyl)DC18C6 as the membrane carrier. The flux of Eu2+ was similar to that of Sr2+ while those of Eu3+, Gd3+ and Nd3+ were almost identical and much less than that of Sr2+. |
