It has been reported recently that lariat crown ethers with an attached carboxylate group and a suitable cavity size can be made highly selective for the extraction of trivalent lanthanides (1,2). The extraction is reversible with respect to pH and requires no special counteranions. This report describes a simple chromatographic method of separating {sup 90}Y from {sup 90}Sr by using papers impregnated with ionizable crown ethers sym-dibenzo-16-crown-5-oxyacetic acid (I) and its analogue 2-(sym-dibenzo-16-crown-5-oxy)stearic acid (II).
