摘要：

The performance of a novel tetradentate hydroxamate as selective metal ion carrier across liquid membranes has been studied. Two types of carrier impregnated membranes have been examined, bulk liquid membranes and supported liquid membranes. The dihydroxamate was found to act as a selective carrier for Cu2+ ions in both types of membranes with antiport of H+ ions. Considering the small carrier concentration in the membranes (0.3 mM), the membrane separation factors and ion transfer rates are feasible and encourage the development of selective membranes for metal ions other than Cu2+.
